You said that, for example, Tor could do things much better, but you didn't put forth any argument as to why you think that/how that could be done. I am not claiming that it's impossible, I am simply rejecting your unsubstantiated claim, and in particular your unsubstantiated criticism of the Tor project. Also, I strongly suspect that any ideas you have in mind have been considered and rejected by the Tor project for very good reasons ... but you'll have to show your actual ideas before I actually know.
Also, it's a useless argument to posit an end user who is willing to do anything they are told by an untrusted third party as a useful threat model. There is nothing that will protect against that, and that includes established ISPs.
