Eve is specifically designed around trading real world currency for in game currency, and that makes a huge difference
As for Aion, I can't speak for the rest of the world, but I don't currently buy gold from the farmers. It's against the spirit of the game, I don't want to support them being in the game spamming everyone, and I'm not about to give personal info to those jackasses.
However, if NCSoft sold in game currency, that would eliminate most of my compunctions about not purchasing gold and I would most definitely be buying a big chunk of it. And I can't help but believe there would be a lot of other players who would take advantage of that as well. Some to much more extreme measures that I personally could ever afford.
Something might go for 50k on the auction houses now with the black market of gold trade. If that market were to become more mainstream, those prices would have no where to go but up. Possibly to the point where anyone not spending additional, real-world money on virtual currency would not be able to afford anything from the player markets by simply playing the game as designed.
