What's really fun is that you can do this with anything, e.g. lawnmowers. I might own one, I lend it to Bob. Now how many lawnmowers are in circulation? Certainly I own one, I have an IOU for one lawnmower. And of course Bob owns one, he's mowing his lawn. If I swap out my lawnmower IOU for some cheesecake and a Tijuana Brass LP, now I'm creating currency and inflating the money supply, since really anything can be currency, ask all those people swapping around cell phone minutes. I think this is confusing for currency because the IOUs look so much like the real thing.
