Or, you can use a browser or plugin which blocks a fairly-accurate blacklist of ad tracking cookies, and not involve the sites’ dubious assurances that they’ll respect your requests for privacy into the equation at all. That seems like a way, way better way. If you want to go past that I would just configure the browser to reject cookies except from a whitelist of sites you trust, and still not involve the site’s assurances into it.

I think the EU overall does a great job at doing consumer protection and I think the “you gotta have a cookie dialog” is one isolated aspect where the law does nothing but create hassle for everyone involved, but I don’t really know; that’s just my uninformed opinion.
