Privacy

For data brokers, you can pay to have various services just run around and keep requesting that said companies purge data about you. They just full-time implement automating opt-out and deletion requests. E.g.:

https://en.wikipedia.org/wiki/Incogni

Incogni is a subscription-based personal information removal service that automates opt-out and deletion requests to public and private data brokers on behalf of users.[1] The service was created by Surfshark in 2021 and launched publicly in 2022; it was later offered as a standalone product.[2]

That being said, I'd imagine that if enough people do something like that

and setting aside the rather ludicrous situation that requires it

at some point, you'd just see data brokers operating in locales that aren't subject to requirements to honor such requests to insulate them. I don't think that it can really be a solution for society as a whole.

I'm pretty sure that a realistic whole-society solution needs to involve not leaking information in the first place, placing technical barriers rather than legal ones.
