A blanket ban on third-party cookies or third-party scripts is not enough. You need to be able to specify which third-party domains are trusted. There are lots of decent sites that need to be able to load assets from a different domain in order to be functional, but which also like to load Google Analytics, or set cookies from Omniture (2o7.net). These aren't ads, but are still things I'd like to block.
Many sites also break if you don't load GA, hence the need for surrogate scripts. If you dismiss and don't try to support the secure use of sites that exhibit any of the above behavior, then your browser doesn't have anything to offer users that care about privacy and security. Privacy doesn't have to be the antithesis of compatibility.
