Pirating isn't stealing though, it's mere copyright infringement. That said, you will always have people that would prefer to get something for free as opposed to paying for it. Really, who wouldn't? The fact that used markets exist and thrive show that people think game prices are too high. Punishing the paying customers with thick-headed DRM isn't going to sell more games. In fact, these companies wouldn't be loosing out on so much cash at all if they wouldn't drop such big dollar amounts on developing copy-protection schemes that don't do anything but annoy legitimate users.
