People seem to implicitly think the world works like in a video game: as if NPCs have unlimited supplies of hardcoded goods available at a fixed price. In an MMO, if you printed enough gold, every single player could buy a whole houseload of healing potions. That's not how the real world works, though. You can't eat cash, nor are there machines that magically turn cash into food.
