We could put a stop to marketing redirects tomorrow if we didn't allow redirects to set cookies.
(Or perhaps only allowed a cookie if the redirect was served by the same domain as the target domain.)

I personally would not mind but I'm pretty sure that a lot of monied interests would not like to see this happen.
People want analytics information, and the only way we can do this now is by adding things like this. (Not strictly true, but ease of deployment, etc).
Unless you shut down the only way to do something, the people who want this service will work around whatever restrictions have been put in place, and the solution we get will probably be even uglier.
The real way to get rid of this is to provide a mechanism that addresses everyone's desires.
it's a social problem, not a technological one imho.
Click count statistics, time-clicked, and geo-information can all be gotten without any cookies. Some sites use url shorteners just to see clickthrough statistics, which can always be determined with no cookies etc.
