I'm actually pretty OK with this. I doubt it will happen, though. There must be a better way.

For example (and this is just an example from my own life), right now, the only thing I can do is block everything, there is no way for me to communicate my actual preferences to site owners. I used to white list sites I really enjoyed to give them some revenue, but with every ad network creepily tracking me, I don't do that any more. No matter how much I trust the site and respect the site, I can't trust their ad network.

What if you could approve ads, but block tracking? I'll allow you to insert some content into my pages that advertises to me, but I won't let you execute JavaScript to do it. The ad is less valuable, but it is better than nothing. If I allow tracking, I see fewer ads (but get tracked), if I just allow ads, I see more ads, but don't get tracked.

There are surely other, better ideas as well.
