When people ask me 'are you hiding from the government' it's almost hilarious to me. I pay local taxes on property, I send the government tax forms every year, I vote prolifically in local and national elections. I have a calling and letter writing 'campaign' for my representatives to know just how much they are screwing up. I go to protests. If I were a person of interest, they'd come visit.
However, there is no requirement to overshare with anyone, and that's where I am. I am not 'hiding' from anyone. I'm just pretty stingy with my data. Now, I realize there are some who must hide from their government, but to date, that's not really in my threat model.
