““Nearly every aspect of modern civilization has been flattening down except one: money. Minting money is one of the last jobs left for a central government that most political parties agree is legitimate. It takes a central bank to battle the perennial scourges of counterfeit and fraud. Someone has to regulate the amount of money issued, keep track of the serial numbers, ensure that the money is trusted. A robust currency requires accuracy, coordination, security, enforcement—and an institution that takes responsibility for all those. Thus behind every currency stands a watchful central bank.””
