Your argument sounds either as if people are obligated not only to watch ads but to change purchasing decisions based on them or the less gullible people ought to pay more.

I'm not even sure how to effect the latter without making the current fish bowl infinitly more invasive.

Even your choice of words is revelatory of a profoundly scewed perspective full of imaginary obligations. Of course those whose livelihood depends on a particular arrangement often seem to feel that the current state of affairs is necessary to the world at large as if the current good effects are both essential and couldn't be achieved any other way.
