Why is it against the summoners code to sell your account?
I've read through their reasoning but I want an honest answer from an actual player not someone who is in it for money. What is the moral problem with selling your account for a game you're dissatisfied with. Upon purchasing items for your account I'd assume you do it purely because you enjoy the game at the time. Once the game changes to a game which you no longer enjoy because the game lacks any resemblance of balance why are you not allowed to sell your account.
Edit - Let me make it clear. I don't want to sell my account. I simply want to know what reasoning there is for selling it being against the summoners code other than a monetary reason. Because lets assume you're correct that they'll lose potential monies due to specific skins being purchased on the account but what if it were skins which were no longer for sale? The potential security issue is a point I find interesting because its one i hadn't necessarily considered although I don't believe that riot is that altruistic.
