That’s probably legally true in the US, but is that the best we can do?
It’s valid to question the value of laws. Sometimes I wish I did have more privacy in public.
But more importantly, technology has completely changed what non-privacy looks like and is tragic to me that laws haven’t caught up.
There’s a huge practical difference between “someone within 100ft, probably a neighbour who I know, might hear me and probably instantly forget what I said, but 99% of the time no one is there” and “100% of your conversations are recorded, transcribed, and stored forever by a profit-maximising behemoth with various other unavoidable tentacles into my life, and also they might sell or give that data to other companies also the police”.
