It’s hard to do a really good job on anything you don’t think about in the shower. - Paul Graham

This is why so many of the best programmers are libertarians.

If showing movies in theaters wasn't Hollywood's original business model, it would seem a pretty niche idea. Pay to watch a movie at a set time in a big room with a bunch of other people? Someone proposing this would have a hard time getting studios to take the idea seriously.
