Someone Else Owes You.

Money is theft through a scam or ponzi scheme.  It is an iou not an actual good or service.  The iou never need be repaid because it is created out of nothing.  For example if someone gives you a sand dollar for a sandwich.  The sand dollar is worthless except to trade with someone else but the sandwich can be eaten.   However even though nothing of value was given for something of value the person who paid nothing of value for something of value need not repay because he already gave the sand dollar on the promise that someone else would trade the otherwise worthless sand dollar for something.   That is why it is not an iou it is a sou or a someone else owes you.  So someone gets something from someone on the promise that a third party will pay them something useful without consulting the third party or giving someone something useful.  I am not saying the sand dollar animal has no value but that in this context that the remains of the sand dollars body are only used for trade.

A Ponzi scheme (/ˈpɒnzi/, Italian: [ˈpontsi]; also a Ponzi game)^[1] is a form of fraud that lures investorsand pays profits to earlier investors with funds from more recent investors.^[2] The scheme leads victims to believe that profits are coming from product sales or other means, and they remain unaware that other investors are the source of funds. A Ponzi scheme can maintain the illusion of a sustainable business as long as new investors contribute new funds, and as long as most of the investors do not demand full repayment and still believe in the non-existent assets they are purported to own.
