Reality check.
No matter how far anon tech goes the government can still fuck you if they want. Anon coins will never be legal tender so you will need to put fiat in and out and explain where that came from. Governments can't decrypt the tech but they can still control every place where you can exchange $ to BTC.
That's called progress. Lots of things just don't work, never catch on, or get crushed by the status quo. A few succeed, to varying extent. Many end up giving future innovations some degree of inspiration and building blocks. But the key is that, even though the odds are firmly against you, it only can ever work if you try.
