Then maybe we shouldn't be making laws to force things "we happen to like" to everyone

It's one of the few ways to negotiate back against contracts of adhesion. Giving that choice would theoretically be nice, but the status quo makes it not really a free choice, and the downside is bigger than the upside.

I don't think GDPR forces you to choose not to share information. You simply get a a mechanism to make that choice.

IMO it is a flawed and wonky mechanism.

Still I'd prefer a the option, later if nobody cares then maybe remove the choice.

It forbids the exchange of information for providing service. There is no choice
