That's already a solution to cookie banners: the "do not track" setting. It's been tested in court in Germany and confirmed to count as rejected permission for GDPR purposes. Websites dinky have to obey it.

It's currently slowly gaining traction, there's a privacy advocacy group suing high profile targets over this to create awareness.

We also need a formal change to the cookie law/GDPR to acknowledge "do not track" as the preferred method. Then the banners will slowly go away.
