Piracy isn't about Joe giving the video to his friends precisely because of DRM. If it was trivial to click 'save as' and copy the movie to a memory stick, I think people would be swapping movies routinely.

I already outlined precisely how they limit the influence of illegal download sites: ensure that the effort to find them and the perceived risk of prosecution and malware exceeds the cost of getting the movie legally. Once people start working and appreciate the value of their time, it's not actually very hard to tip that equation in their favour.
