OK it's time to stop conflating piracy and used game trading. They are as unlike to each other as rape is to casual sex. One is illegal the other is not.
If people don't want game retailers to make profits off used games then there's always e-bay, you get a better price for your game by selling it yourself than by trading it in to a re-seller anyway.
There are games that have not sold well that I think are great. But a game should be able to stand on it's merits by attracting a large enough audience into buying the game new. I buy plenty of used games. The used games I buy are those that aren't available new (like Heavenly Sword) or that there is simply no way I'd by new because I only have a slight interest in playing them so they are not worth the new price to me (like Resistance FoM). No one is missing out on a sale from me, if the game isn't available used I won't buy it at all. The good thing about buying used games is that normally their SP / local co-op or multiplayer provide sufficient value that the lack of online wouldn't be a big deal for me.
If you can't convince me to buy a game new now, then trying to stiff me by restricting gameplay options unless I pay extra with a used game isn't going to convince me either to by new, or to pay the extra to fully utilise a used copy.
I also sell my games I don't play/want anymore to realise some cash in order to buy more games. So the used game market indirectly supports the new game market anyway. So the money in the used game market isn't completely lost to publishers and developers.
I don't support cracking down on the perfectly legal trade in used game. I do support cracking down on software piracy.
