Sure, it sucks that you can't resell games that you buy on Steam, but this isn't anything new. If you actually read the EULAs on the games you buy, you'll notice that most of them say something along the lines of "_____ grants you the non-transferable right to install and use the product..." which means that, Steam or not, what you wanted to do was illegal. By agreeing to an EULA that has a non-transferable clause in it, you give up your right to resell that game. The only way to legally resell a game is to do so before you've agreed to the EULA (before you've installed it), which sucks, but it's not the game company's fault that nobody reads the EULA. Likewise, it's your fault that you didn't read the EULA for Steam when you signed up. Nobody did anything wrong here except you :P
