Player A wants gil and has disposable irl income. Player B has gil but wants to supplement their irl income by paying their sub in gil. SE wants money.
How are the two players in this exchange not benefiting from the exchange? Sure, SE also gains something... is that somehow a negative to you? Do you hate the game so much that you don't want SE to make money now?
I'm not saying this is a good idea, I haven't yet given it a ton of thought, but to say the players aren't benefiting is just nonsense.
