You could simply ban targeted advertising, since that's what everyone is actually upset about, and not create insane collateral damage for non-adtech operators who happen to have network services and databases.
So it's not everyone, is it even most people? I'm not sure.
I do feel for you if you happen to live in the EU, but you get what you vote for. I don't live there, none of my businesses operate there, so I'm free to ignore it. The GDPR ends where the EU does, and cross-border enforcement of laws requires a bilateral agreement, that I would have to vote for.
I think there are many people who are fine with targeted advertising and also fine leading a private life in non-GDPR jurisdictions. I think that covers most people in the world.
Given the amount of ad-revenue services I get access to, it's a very good tradeoff for me, please don't kill it, and if you do kill it, stick to your own jurisdiction please.
