I think you may have misunderstood my comment. I meant that the "consent forms" should be a browser-side feature, consistent across websites and such that things like cookie blocking are guaranteed to be honoured. This is trivial. Things like server-side fingerprinting must be enforced through legislation, e.g. it's against the law to track users if they've selected not to in the consent form.
