Substantial amount of various systemic reforms would be required to reach this. Election reform, voting reform, constitutional reforms (to the point a new one would probably be necessary), and so much more. All while, like you point out, dozens if not hundreds of thousands of people, politicians, legal frameworks, and corporate interests would work to undermine, delay, or prevent these reforms.

They are possible. But it isn’t easy. I just feel, that what cryptocurrency advocates want is really a right to privacy. That the current systems do not have. A currency using a hardcoded hyper deflationary monetary policy and is barely able to make a fraction of the current rate of fiat transactions is hopefully not what they are actually after.
