not everyone has a decent computer that can run the latest games. Some people just don't have that luxury. There are a lot of people who are still buying GBASPs and PS2s because those are affordable. As long as there are people who aren't willing to drop money on high speed internet, a decent gaming rig/the latest console, new games, there will be a market for physical copies and home consoles. When you are on Steam, you have NO option of buying a game used. Don't quote me on this one, but I don't think you're allowed to even use used PC games... There just isn't enough of a market to actually warrant a trade-in system.
