The issue is still not with allowing users to sell back their product. The problem is with Game Stop turning around and reselling without giving a single cent to the publisher. With a used game, they don't have to. It's perfectly legal with any 'used' product not to give money to the original producer. When you sell a game back to Game Stop, none of that money goes to the publisher, so why would you think the publisher gets money when Game Stop sells it again?
As for those claiming that it won't cause any problems, imagine the following scenario:
An indie game (Let's use Bastion) gets released. A fair number of people buy it within the first couple weeks. Since Bastion can be beaten within a few hours, most of the players will finish it fairly quickly. Then, 50% of them sell the game to Gamestop. So the publisher has sold X copies at this point, and Gamestop has X/2. Now the next X/2 customers that buy the game will all buy it used, because there is no reason for them to buy it new. So at this point, Gamestop has sold X+X/2 copies, and paid the publisher for X of them. Moreover, it is likely that this 50% sell-back number will remain constant or go up. So we now have X+X/2+X/4+X/8+X/16 etc copies that can be sold by Gamestop while only paying publishers for X copies.
I don't know about you, but I'm pretty sure a game developer deserves to receive a cut of all sales made by a major retail chain, not just 2/3rds of them. This is especially true because it's not protected your consumer rights unless the options go beyond "sell to Game Stop" and "Keep forever". If you can't sell it to your friends, you're not really gaining any rights beyond the right to help Game Stop rip off developers.
If this used thing becomes prevalent, major publishers will take action to avoid it. I wasn't trying to justify what they've done so far, but if you think they won't do far worse things when used digital becomes a thing, you obviously aren't very good at pattern recognition.
Also: A quick flip through of Green Man Gaming reveals that there is a very very large number of games which cannot be traded in.
