Basically this comes down to do companies have the right to control the media they sold after the consumer has bought and payed for that media. The answer is no. Once the person has payed for the media he/she should have the ability to do whatever he/she pleases with it short of selling or distributing copies of the media. In the case of video games there are other ways to prevent people from installing a game onto a friends computer, allowing the friend to play the game without actually transferring ownership. One of these ways is through having a disk check when starting the game, so that only the person with the disk could play the game. If piracy is to stop the only way to do it is by going after those who distribute the pirated media. If people can't find a source to download a pirated copy of any kind of media they don't have a way to get their hands on the media short of actually paying money for that media. Finally I would like to add in the case of music the reason for so much piracy is because of poor business practices and overpricing of material.
