It's not about believing. It's about a lack of alternatives.

There is no real meaningful competition between money systems. Every nation has one national money system and it's a government mandated monopoly.

Your options are basically complete autarky or using the national money system with nothing inbetween. Even if you were to use a cryptocurrency, you'd still need to pay taxes in USD.

Then there is the fact that cryptocurrencies don't really meaningfully change the rules either. You're supposed to accumulate them forever and profit off of latecomers joining in it at inflated prices. Meaning the supposed competition just amplifies the worst part of money that people would rather get away from.

Anyone who earns an income from work is by definition going to be a "latecomer" by the end of their career. Basically, you're defining yourself by the first few years of your career, e.g. buying thousands of dollars worth of BTC in 2013. By 2026, there is not much point buying more BTC.

Money is given an inherent bias towards the past being more important than the present or the future, which thereby inevitably causes the collapse of the future, which then becomes the collapsed present through the simple passage of time.
