We are forced to value bank credit if we value cash

If people learn how banking works they might take a different view with regard to the value of fiat money and bank deposits... but that doesn’t mean banks print money now. Unless the government prints money which they do not. Fiat money is impossible because the government is not powerful enough to alter prices.

Someone who mines fool’s gold is not mining gold. We can be fairly sure people do not value bank credit for its own sake so in that sense it is a trick.

The government have an obligation to prevent bank inflation.
