I agree that bitcoin doesn’t necessarily give you freedom. I think it’s a tool that can help you get freedom so I still refer to it as freedom money. But getting freedom comes down to the efforts of the individual. His mentality, his understanding of people that can hurt him, and the time he puts in to preserve his liberty. But I disagree with your other point. I think eventually fiat dies and governments won’t be able to afford to surveil everyone. It could get ugly before that happens and the ones that didn’t prepare, won’t have that freedom. 

Idk if you read mandibles but toward the end of the book, the protagonist realizes that the country couldn’t actually stop people from leaving to a different jurisdiction that offered more freedom. They could only use propaganda to scare people into thinking their chips would self destruct and kill them when they crossed the border and that the other jurisdiction was a crime infested and uninhabitable disaster. They also couldn’t afford to keep military or police forces at the border to stop people from leaving. He realizes that it was all a bluff because they couldn’t afford to do anything more.
