If the government was interested in your illegal transactions, they would find you, and they would take everything you own in recompense if they wished. Your 'anonymous' wallet will not save you if cryptocurrencies actually become important.
If you want to stop that, you need to consider what a revolution entails - civil disobedience and breaking unjust laws en masse and standing up to the state in the real world, not just in code.
I have some sympathy as I have the same approach to online identity (don't bother as anonymity simply isn't realistic), but if working for a company that recently had to flee US jurisdiction I'd be more circumspect about advocating breaking the law!
It's almost impossible to be anonymous to a nation state even if you try harder than us anyway, and most people slip up early and often - you won't know you want to hide from a state till it is too late in most cases.
Though given you are posting your thoughts on defying the state and avoiding taxes in detail under your real name here and probably elsewhere, I'm not sure dragnet surveillance would be required.
