I think it will boil down to there will come a point where the governments, no matter what they claim to stand for, are going to be threatened by the freedom people have. The desire will be to reign that in which means turning against crypto.
We see this in Russia. The government is using it to get around the oppression of the West yet, turns around, and wants to control what the citizens do with crypto.
The numbers simply have to get to the point where it is overwhelming against these governments and they basically cannot do anything.
It is that way with file sharing. The USG had to give up because it was so common. Strike down one site, two more show up.
I pretty much agree with everything said here but I think there will be a further trend that clearly shows allowing the population to freely use crypto generates an enormous amount of value.
So the question starts becoming: how long will it take for the value of crypto to surpass the value of unilateral control? We all know how easy it is for politicians to be bought and sold. We're already seeing crypto money make a huge dent when it comes to manipulating policy. It's only a short matter of time before that influence expands exponentially with these market caps.
