I've never pirated because of my morals, I know I won't get caught but I also know it's illegal. I think some people are like that too and don't pirate for that reason.
But another thing is, if your rich and have an often sound system, why not just go out to the movie and spend some more money? If you have a medium amount of money, you won't have an insane awesome sound system and tv and You'll want to go out to the theater. Plus, from what I've heard, the in theater pirates are usually shaky and bad. Also, plays had it's time, now they're more of a novelty, and I think they'll stay that way, and I especially don't think they will change because of pirating.
