Where is the profit though? It's like saying my neighbor profits from me never inviting him for a coffee cause he gets to practice brewing coffee every day. He also got about 3500 coffee IOUs from me that are worth about nothing cause I have no clue how to make coffee. How is my neighbor profiting in this scenario and how do things change if another neighbor provides me with beer and another one with fridges if I'm only a lazy bum printing IOUs. My neighbors using **my** IOUs to trade among them doesn't make things better but that's what the world was doing.
