Sorry for the brevity, but the only thing I can think of is: A-fucking-men. This is a colossal waste of time and resources, and it's a completely distraction from other -real-, -actual- privacy concerns that every day citizens should have. This is not one of them, and there is already a solution.
Actually that would be a good potential solution to have cookies on browsers automatically disabled but one that advertising networks and companies that rely heavily on advertising revenue (Google for example) are lobbying hard against for obvious reasons. As a result, I don't think this option will make an appearance anytime soon.
