Bitcoin, or it's successors, makes paying the State an entirely voluntary affair. They can't even prove how much you've got. When people cannot be forced into paying the State, the State must convince them to pay. That puts them in market competition, if not with each other, then at least with all the myriad other things money can buy.
Hogwash. It's easier to "prove how much you've got" with BTC then it is with paper fiat.
If by "forced into paying the state" you are talking about taxes, you're just wrong. The IRS could basically work just the same way, making you declare your income, auditing you to prove it, etc.
If by "paying the state" you are talking about using an inflationary currency where the state is the beneficiary, you are 100% right
