I'd rather have no DRM / EULAs on my games either. The gaming industry, however, sees otherwise.
The existence of either DRM or EULAs is not going to keep me from enjoying my games, unlike some people here who seem to be cutting off their nose to spite their face.
In one sense, you are correct. The vast majority of gamers have shown that they don't care how bad the DRM gets, they will buy anyway. However, if ever gamers would reach a breaking point where they wouldn't buy, the developers would back off. We saw it with Starforce, and other absurd copy protection systems that often caused more problems to end users.
Ultimately, the gaming industry depends on gamers, and vice versa. However, as a group, gamers have shown themselves to be too undisciplined or organized to adequately protest the more egregious forms of DRM.
The worst part is the knowledge that all of this crap has almost NOTHING to do with "piracy" - that's just a red herring to keep the Congressmen happy. That's not to say that pirates aren't considered when it comes to DRM, only that pirates aren't the primary target. Most of these schemes are designed to protect a title for the first few critical weeks when sales are the highest. If it can keep the pirates at bay for a month, it's probably considered a huge success.
So, why don't publishers remove the DRM when its broken? Because the DRM is really intended to destroy resale value more than stop pirates. They want every legit player to pay *them*, not you, not GameStop, etc. Most game publishers, except possibly Ubisoft, knows that the pirates will rather quickly break the protection and enjoy the game without paying - but I firmly believe that they also know that those players are a lost cause. Those guys aren't going to buy no matter what - so they really aren't "lost customers" The real lost money comes from players selling their used, but otherwise legit, copies - which is why I only see this getting worse.
Steam is a perfect example of this. You can play all you want, and buy cheaply, but you can't sell anything. You can't even sell your account. Gone are the days when you could subsidize your next game by selling your current game.
