Advertising isn't fundamentally bad for privacy, otherwise newspapers and movies would be bad for privacy; it's targeted advertising (which requires keeping a profile for each user) that is fundamentally at odds with privacy.

Well, advertisers are going to do their job as well as they can, defined by the amount of money their methods bring. They can't track in newspapers or movies because there's no feasible way to do so. If you want a business to not do something that brings it more money, you'll have to introduce legal liability that makes that something not worthwhile. That's probably GDPR, in a nutshell.
