Sadly, I can't see that happening anytime soon. The organizations who have a vested interest in all this are just too powerful and can afford to pay for better lobbyists.

EDIT: If anything I can see publishers and advertisers trying to lobby for DMCA style laws that will make it an offence to circumvent tracking and profiling. They can spin such techniques as just an attempt to generate revenue and to circumvent them is as bad as music or software piracy.
