Government intervention and a massive change in how digital content is managed would be the only real solution. When governments get pissed off enough at the lost revenue (of which porn is a tiny fraction, as compared to software and mainstream media) they will sit down with Intel, AMD, Motherboard manufacturers, etc and solve the problem from a hardware part of the equation.
Until then we are left having moral arguments over whether someone should or should not do something regardless of whether they are able to do it or legally allowed to do it. Those tend not to have teeth, especially in a tight economy.
