But maybe most governments don't ban Bitcoin because they see how robust it is. Historically they have failed to stop people from taking drugs, including drinking, or downloading pirated content and so on, so instead of banning Bitcoin they hope to discourage people from using it while keeping an eye on those who do by regulating exchanges and requiring KYC. So far it works because a lot of users don't care about their privacy and keep using those exchanges and avoid privacy-related practices like mixing.
Yep. There is enough historical evidence that certain things just can't be stopped, and especially not when it comes to P2P applications. Bitcoin is like an open book that contains permanent loggs.
It will help the government link your activities back to you, even if it's like 5-10 years later, and that's what they like. They know where you buy Bitcoin and when you spend it, they just need to prove that what you did was illegal.
Eventually the entire centralized ecosystem will be filtered by authorities and we can't do much other than to watch our steps. Right now we're ahead of that, but we don't have much time left to use dex's and free ourselves.
