I actually considered this question and after thinking about it, despite everything going on, I think it boils down to lack of privacy as my biggest gripe in the modern world
It’s such a tough concept to explain to the if you don’t have anything to hide crowd, but if someone wants to disappear, I don’t care if for good or bad reasons, they should be able to
If you don’t want the government on you, if you don’t want people you know to find you, if you just want to reinvent yourself, it doesn’t matter why - you should be able to do this. It just “feels” like an innate right. Normally I don’t like to argue using “vibes” as justification, but this to me is just part of my value system/morals which is inherently arbitrary to begin with
Encroaching on this privacy encroaches on a bunch of other rights, like free speech as you’ve mentioned
The fact that this is the case makes it even clearer to me that privacy is a basic fundamental primitive
Would love to hear alternative perspectives and other justifications for or against privacy
