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.

You can learn how to minimize it.

Enough said.
