At this point a cash shop selling tradable items wouldn't be that bad of an idea. There isn't any fairness anyway. Right now if people want to buy gp, they can just go and spend their money on any website that sells it. That money ends up in the pockets of botters and account hijackers. If Jagex opens up a cash shop that sells the usual items: xp boosts, costumes, power boosts, pets, etc, which can then be sold in-game for money, it legitimises RWT. People will choose to do this over buying black market because no risk is involved. All the money that would otherwise end up in the pockets of rule-breakers would end up in the pockets of Jagex. Jagex who could then use that money to better the game and give us better updates. You can't stop rich people from buying their way into things, but you can choose where the money ends up.
