I'm curious what the technical solution is you're proposing. I was considering OP's context of a technical solution that's "clearing your cookies regularly". Surely that's both not sufficient (not by a long shot) and being tried at some scale [1]? So probably you mean something else, but I'm not sure what.

First step would be making private browsing the default. Second step would be making strong, capable adblockers built-in. Third step would be something like Firefox containers, one for each domain. Fourth step could be analyzing network traffic for potentially fingerprinting information and blocking it. I am sure there is much more to think of.
