Money Is a Technology of Trust, Not a Measure of Life
One of the most fascinating human abilities is our capacity to collectively believe in abstractions.
Religion can be one. Moral principles can be another. Money is another. Across vastly different societies, human beings have repeatedly organized themselves around ideas that cannot be reduced to physical objects alone. The fact that such abstractions appear so persistently across human civilization says something important about how our species cooperates.
Money is an especially remarkable example.
A banknote has little direct use value. A number displayed in a bank account has even less. Yet both can be exchanged for someone else’s labor, food, property, knowledge, or time because people collectively accept that the claim represented by money will continue to be recognized.
The physical form of money has changed repeatedly. Ancient societies used commodities and accounting units; coins later standardized transferable value; paper money separated monetary value even further from the material carrying it; and today, most money in modern economies exists as bank deposits rather than physical cash. The form changes, but the underlying function remains remarkably persistent: money allows claims on value to move between people and across time.
In that sense, money is one of humanity’s most successful technologies of trust.
But money and value are not the same thing.
Earlier economic thought often tried to connect value closely to labor and production. Modern economics increasingly came to understand price through utility, scarcity, and what people are willing to give up for an additional unit of something. I suspect that this intellectual transition also reflects, at least partly, a broader change in material conditions. When production itself was the major bottleneck, labor and productive capacity naturally occupied the center of economic life. In affluent societies, where basic material survival has become less constraining for many people, value increasingly differentiates according to individual preferences, experiences, identities, and desires.
This creates a strange problem.
Prices are visible.
Personal values are not.
A market can put a number on an apartment, a watch, a car, or a company. It cannot put a meaningful number on friendship, freedom, love, curiosity, health, or time.
The beautiful sky outside my window and the clouds constantly changing across it give me more satisfaction than expensive possessions.
And they are free.
Some of the most valuable things available to us have no meaningful market price at all.
Yet because prices are observable, comparable, and easy to rank, they can gradually become substitutes for our own judgment. A more expensive object begins to feel like a more valuable object. A more expensive neighborhood begins to look like a better life. Rising asset prices begin to feel like proof that the owner is winning.
Society gives us a scoreboard before we have decided what game we actually want to play.
I see this tendency particularly strongly in Korea. It is easy to become more attentive to what other people consider desirable than to what one actually needs. Housing is perhaps the clearest example.
There is nothing inherently wrong with wanting an expensive apartment in Gangnam. But consider someone who takes on enormous debt to buy one, gives up travel, experiences, books, or time with family and friends in order to service that debt, and eventually becomes afraid even to sell because taxes are high and buying the same apartment again may become impossible.
The apartment may have risen dramatically in market value.
But has that person’s life necessarily become richer?
A bank being willing to lend enough money to purchase an asset does not mean that the asset is truly affordable. If maintaining ownership requires reorganizing the rest of one’s life around the asset, ownership itself can become a kind of prison.
An asset should serve a life. A life should not be reorganized to serve an asset.
Even if I had enough wealth and earning power to buy an expensive apartment in Gangnam, I suspect I would be considerably happier living in a reasonably comfortable apartment in a city such as Daejeon, while using my resources to travel with family and friends, buy as many books as I want, pursue intellectual curiosity, and experience the world.
Expensive cars, clothes, and watches simply do not interest me very much.
For me, the purpose of money is to expand what I can choose to do with my life.
Money can provide safety, mobility, education, privacy, time, memorable experiences, the ability to support people one cares about, and perhaps most importantly, the ability to say no.
It creates optionality.
For someone who can convert financial resources into these things, greater wealth can genuinely make life better.
But the direction of the relationship matters.
Once money stops being a tool for constructing a chosen life and becomes the score by which a person measures his own worth, the relationship reverses.
A person can possess money and still be possessed by it.
This distinction may become increasingly important in an age of abundance.
Many people in wealthy societies already live with access to food, medicine, information, transportation, entertainment, and technology that would have been unimaginable to most humans throughout history. This does not mean competition has disappeared, nor that economic security should be taken for granted. Technological and social change can destroy yesterday’s advantages remarkably quickly.
But for many of us, the central question is gradually shifting from simply acquiring more to deciding what more is actually for.
That makes self-knowledge increasingly important.
And strangely enough, while individuals are being forced to reconsider what value means in their own lives, money itself is entering another period of experimentation.
On October 31, 2008, Satoshi Nakamoto circulated the Bitcoin white paper, proposing a peer-to-peer electronic cash system that could operate without requiring a trusted third party to validate transactions.
Bitcoin has since become the most prominent example of a decentralized digital asset. It is often described as digital gold, but I think that description is still premature.
Its continuing volatility suggests that owning Bitcoin today is not simply equivalent to owning an established digital version of gold. It may be better understood partly as a bet on the possibility that Bitcoin will eventually acquire that role.
In other words, part of Bitcoin’s value today comes from a belief about what Bitcoin might become tomorrow.
This is appropriate, perhaps, because belief has always been central to money.
Bitcoin asks whether monetary trust can be placed less in a particular institution and more in a protocol and a network. Its original design explicitly sought a payment system in which cryptographic proof and decentralized verification could replace the need for a trusted third party.
And Bitcoin is only one experiment.
Ethereum explores decentralized execution and settlement on a much broader scale. Stablecoins combine digital settlement infrastructure with claims on traditional currencies and assets. Commercial banks and fintech companies are developing their own digital financial infrastructure, while central banks are considering how monetary systems themselves may evolve.
I strongly believe that blockchain-based technologies will become an important part of the future financial system.
The future monetary system is unlikely to be one in which one form of money simply replaces another.
I expect it to be a system in which different architectures of trust coexist.
Central banks, commercial banks, fintech companies, decentralized networks, stablecoin issuers, and protocols may each perform different functions. Some systems will rely more heavily on institutions. Others will distribute verification across networks. Many will combine elements of both.
The interesting question, then, is not merely which technology wins.
I am curious about how human behavior and beliefs surrounding the financial ecosystem will change, and how those beliefs, technologies, institutions, and behaviors will continue to shape one another.
But underneath that technological change lies a more personal question.
I believe that a person who tries to understand oneself, learns to doubt one’s own assumptions, thinks seriously about what truly matters, and then chooses how to live can build a life with the depth, layers, and aroma of wine.
Without that process, life can become more like a distilled spirit: concentrated around a few obvious measures, perhaps strong, but stripped of much of its complexity.
The difference begins with knowing what is actually valuable to you.
