Paper currencies seem normal. They seem natural. We are told they are necessary. Paper currencies with no intrinsic value are used everywhere – we pretend they are valuable. If we don’t look closely, or remember the world of 60 years ago, they seem like a good idea.
Monopoly money. Euros. Dollars. What is the essential difference? Paper, with no intrinsic value, is accepted only because we have confidence in the issuer of the currency and/or because we have no other choice. Monopoly money can buy hotels on Park Place. Unbacked paper dollars can buy hotels in Manhattan. The hundreds of unbacked paper currencies that have become worthless during the last century can buy NOTHING.
