Isn’t it already impossible to be anonymous on the internet without flawless opsec? I’m surprised there isn’t a TV Tropes article about it but whenever a character in a show needs to be perfectly anonymous they visit an Internet cafe with a baseball cap and glasses - which while it’s a trope I think it also plays on our cultural understanding that significant diligence is required to maintain anonymity.

Edit: though I suppose the counterargument is that we shouldn’t make it any easier for surveillance states, especially technologically inept ones, to perform dragnet surveillance.
