Appealing to people's better nature is about the same as asking for donations. You aren't gonna get too far.
I think the best anti-piracy approach isn't DRM, but to convert it to a service. You can't pirate a MMOG. Not all software can be tailored to this, but most can, especially in this age of 24x7 connectivity. Software is heading in this direction already, with SaS and of course Da Klowd.
The tough cookie is how to extend the SaS model to media, viz movies and music, given their fundamentally "offline" nature of consumption.
Perhaps the way forward for the movie/music industry is to wrap them in software, eg make them interactive. Say, a piece of music can be played at varying tempo of your choosing, or it can be auto-remixed using templates, or it can be sweetened depending on your mood, etc.
Interactive movie is a tougher row to hoe, since movie watching is mainly a linear experience. But once animation gets to the point of achieving photo-realism, then a movie can conceivably be constructed like a game.
A major weakness of games thus far is lack of pathos. It's hard to be scared, or feel sad or joy, when playing a computer game, as opposed to watching a good movie. Perhaps a movie-game hybrid, with real human actors in intermixed sequences, will achieve this.
