Most importantly PLEX trading doesn't undermine the player economy - You are buying ISK for real money, but only to the extend that other players are willing to make that trade with you. And the goods you buy with ISK have to be made by players and are subject to market rules, and anything you can do with ISK acquired through PLEX someone else can do with ISK acquired in-game.
You cannot acquire goods in arbitrary amounts via PLEX trade, and since EVE has people that don't mind spending mid 6-digit USD figures on the game that is an important thing.
Furthermore there would be the obvious thread of offering things via micropayments that are better than what is commonly available on the market. That's one of the big fears
