Serve ads from the host site.

That's a feature, not a bug. Or another way: users shouldn't be able to 
be tracked across sites. That they are is a bug, not a feature.

Not all such services do require this though. Google Analytics 
implementation decisions are not the only ones possible.

I don't have time to respond in detail to each of the valid points your 
raise.  I may later. However each of them can be handled in a different 
way that doesn't require third party content and mashups. The reason we 
have designed these systems this way is because it was quick and easy, 
not because it was the only way to do these tasks. If we break these 
things such that third party content is no longer the simplest solution 
that could possibly work, then developers and sites will move on to the 
next simplest solution.

The bottom line is that bad implementation decisions made years ago with 
respect to third party content are causing security issues now. We can't 
paper over these problems. Anything less than addressing the root cause 
will fail.

Addressing the root cause will cause pain because a lot of systems you 
mention will have to be rewritten to work in the new world. So be it. 
Nothing else will work, and the sooner we recognize that, the sooner 
everything will be fixed.
