I believe the system where a semi-independent central bank has the ability to regulate the currency of the country is a good thing on the whole. It's the best balance of compromises we have seen actualized.
Having a fixed supply of digital coins seems more like a return to the old days where there was a fixed supply of gold and silver coinage. And that era was called the dark ages. A system with fractional reserve credit is much more conducive to economic growth and prosperity.
I'd also imagine that crypto ownership is massively concentrated in the top 10% wealthiest people anyways.
Sorry to burst your bubble, but cryptocurrency does not work this way. Your reasoning can be applied to any asset, for example, a shitty house in California that is now worth $1M.
