Don't think so. But a global currency that a country's bank cannot print, would be good. So governments wouldn't easily manipulate markets, they wouldn't have much power on inflation (I mean they need to find better solutions when they're constrained.)

Also tax is a thing. In crypto world, how would a government official collect taxes? You own your wallet and they cannot do anything about it. (however they can do things to your bank account) They may get taxes from your employer, but still, not every job has an employer. What if people work online and get paid in crypto? No taxes then. Don't know. There must be something we can't think of right now, and probably that option will happen
