You can still derive a lot of info without having possession of the data through the use of PETs. There's a reason why companies like Google and Tik Tok make heavy use of PETs for their advertising products.

An environment like that is where SOLID, or something like it, could thrive.

We could just start to enforce the laws as they're written.

If I was to follow a stranger as closely as an entitty like Facebook or Google does and compiled a dossier on that stranger in many countries that would be considered stalking and would be illegal.

Incorporating and doing the same thing to society en masse doesn't somehow make it legal despite it somehow makes people disinclined to prosecute.
