We need more ways to make gold in this game.

And I suppose you could avoid repairing your gear, but then your performance would drop like a rock.

Battle-class only individuals (or people with limited crafts) suffer from this. Anyone who's maxed all of their crafting and gathering jobs can easily get by without needing to buy repairs from NPCs. So this is fairly moot.

But the rest...yeah. I'm inclined to agree with the OP on this one. Every way that they've given us to make money outside of playing Market Mogul is not enough to sustain the economy. Especially since selling an item means 5%~10% of that gil just ups and vanishes, and never makes it to the seller.
