What if ghostery could make the trackers unable to continue tracking without blocking them?

Edit Subject

There is a way to hide some private data without having to block the content at all. It won't be as robust as not loading the data, but it can be used to give security in case of trackers that are not listed by ghostery yet. (in short: there is always a risk and I want to be safe)

I'm thinking of loading third party elements (iframes, images, scripts, ...) with a clean state each time. No cookies, no cache, nothing. The 3rd party would also be denied to change the global browser state. Each iframe or image would have a completely independent cookie jar, and cache.

I'd imagine this a bit tricky to implement, but why not?
