You can have decentralized money without crypto - just use gold parity - but somehow no country uses it now. Maybe they are all corrupt - but maybe it is just not good way to manage the economy.

And maybe it's not, and the government is taking advantage of it's position of power?

Competing tethered currencies aren't gone because they're a bad idea, they're gone because they've been made illegal.

Crypto gives the power to operate such a currency back to the people in a way that can't be stopped.

> just use gold parity - but somehow no country uses it now.

Thats fine. If you don't like deflationary currencies, then feel free to not use them.

Other people disagree, though, and are preferring deflationary currencies.

Everyone can get what they want.

It's worth noting that because of the power the U.S. has over global finance it's hard for other countries not to follow its lead. So when Nixon went the route he went, the rest of the world was to a large extent forced to follow suit.
