And in the offline world - pay for things in cash. Government is lazy and they love being able to search everything. Sending people to actually investigate things with actual leg work is not ideal. Paying in cash, or doing anything physical (pen and paper, in-person talking) breaks everything.
which is why laws are being made to prevent large cash transfers. I won't say which country i'm referring to, but it sounds like a police state. I'm terrified this will become the new reality. Bitcoin to the rescue? I shudder at the thought.
And live in New York City? Probably the one last city where you at least have a chance at being anonymous. The train station camera coverage is a joke.
