We both know that legitimizing the RMT system increased the number of gold buyers and normalized the process

Really? Where is your data to back that up? Games like old school RuneScape and World of Warcraft still have people who buy gold and get banned for it all the time. You’re also conveniently disregarding lots of the benefits of this system. People can now earn currency fully in game to pay for their subscription. Completely for free, and other players are making a choice the purchase the tokens. There’s virtually no pressure in game whatsoever in World of Warcraft that prompts you to purchase them. There’s no pop-ups, no advertisements for tokens at all. This is the least predatory form of microtransaction I have ever seen. Compare this to Destiny, in which you are constantly given currency for free to use in the eververse, and repeatedly going there back and forth being flashed with bullshit items that you’ll never have enough currency to afford.
