If that were strictly true, Bitcoin heists would be impossible. And, in principle, I suppose one could photograph every dollar one ever had and get at least as good results.
US dollars have a unique aspect: US taxes must be paid in US dollars = not euros, yen, pesos, loonies or bitcoins. The US spends $6T a year in federal spending, and states about $2T on a GDP of about $25T. So about a third of the US economy must be on dollars.
Given that, what does Bitcoin buy you?
- The ability to buy things you don't want the government knowing about.
- Stonks only go up! Bitcoin too!
Neither seems a compelling reason to switch away from dollar when buying a gallon of milk. In the US, crime is a few percent of the economy, so there is little use of Bitcoin day-to-day. Only when you want someone whacked.
That leaves "stonks always go up" - with no underlying asset and limited purchsing ability,. the only point is the Greater Fool Theory. Get in now, and sell it later to someone else. Historically this has not ended well. You won't want to be the one standing up when the music stops.
