SE might want to keep the steady inflow of money coming in from them, rather then risking the RMTs just abandoning this game because they can't make a profit from it.

Just speculation and possibilities, none of us know for sure what on earth SE is doing.
RMT don't actually buy all their accounts, a lot of them are hacked, quick password change and a character can be stripped in no time. Even people who are careful can get hacked, all it would take is a major fansite to get hacked, and malicious code inserted and we could have a hacking outbreak like the old ffxiclopedia hack. Hacked accounts are free gil for RMT, best thing is for everyone to stop buying gil, but we know that won't happen.
