like GDPR, but cookie banners are by law preemptively answered with no

Its not just cookies. If you tell an LG TV that you live in Europe it will ask you if you want to turn of these “intelligent features“(ACR)

in fact, cookies legible to anything except the single sandboxed webpage running on your local browser would be illegal and thus never exist to begin with

I like it, but we'd need to find a new way to do auth (and then prevent that from being used for non-auth-related tracking)

i mean that the business models of google and facebook would go poooof

Sadly not. Context based ads is a thing.

Context based ads also give away information about the user. Because if you buy the goods that were advertised the vendor knows which contexts apply to you. It is not very precise information and it may involve probabilities, but it is still information.

Yeah and like coupon codes for discounts etc.

That's a vey reductionist position.
