I think, though, that the point is everyone in XIV can make money in different ways, depending on how they choose to do it. They don't have to just take part in the ridiculous NM farming that existed there in order to actively participate in the buying/selling of the economy.
There should never just be one way to do much of anything in a good MMO, and the fact that crafting, gathering, 'and' combat classes can all perform this aspect in their own different way is a good thing.
