Legal solutions for technical problems don't usually work out well. You'll be able to demand what ever you want, what will happen is anyone's guess. Large companies will likely try to follow the law, but purposefully or not, fail to. Smaller companies will totally ignore it, as the evidence that you are being tracked is difficult to collect and probably more difficult to prove in a court of law.

Like someone else said, we need to redo how the HTTP and browsers work to try and come up with a technical assurance that no tracking is taking place. Of course that's easier said then done. And really, I'm not sure it can be done.
