Errr, I'm pretty sure this is his point... These are things you have to earn in the game, that people can now spend real world cash on to get instantly. The fact that the consumables already exist in the game doesn't negate the fact that they can now be bought with money instead of working for them in-game, hence the unbalancing created by micro-transactions that people get pissed about. Your argument would be like saying, in this hypothetical: "Well sure you can buy a Sleeper Simulant for silver, but it's literally the exact same gun I could get by completing the quest."
