You have to remember that most MMOs are not economic sims, they have an economy minigame where people act silly with their virtual currency because it's not real life. Any steps to manage the in-game economy take away from designing more fun stuff that players may care about more. Furthermore, I bet the only reason non-gamers pay attention to this stuff is because of third parties selling virtual currency and goods for real currency, which nearly all MMOs forbid.
