Your best bet is to start reading up on privacy and fourth amendment cases. Privacy is a right legally enshrined with very precise boundaries. Anonymity is not.
That distinction is extremely important because the things you’re describing are not violations of your privacy. Except when you describe coercion which is a different crime.
I want to be as clear as possible: I am not trying to have the philosophical conversation you are trying to have. I am trying to bring your concerns into the real world (which they’re about, tbf) and into the real realm of understanding of that world that the law corresponds to. Because ultimately that’s the lines you need to color inside and out whose geometry you need to be aware of.
Aside from actually answering the question: What are you trying to accomplish and where? Which no one will do, that’s the most help I can offer.
