That's almost what banks actually do. In the Federal Reserve system a bank can literally write new money into existence with a flick of a pen.<p>What you're spending on food, rent, and iPhones day-to-day is a substance called <i>bank credit</i> that sprung into existence when someone, somewhere, applied for a loan. When they spend that bank credit it goes into circulation and eventually winds up in your paycheck.<p>The issuing bank doesn't need to find real money to service that credit until they either have to correct an imbalance with another bank (call for a Brinks truck), or increase their deposit with the Federal Reserve to cover their mandatory 9:1 credit ratio.<p>It's all paper money and bits now.
