Fiat Currency allows for the Government to print away the value of people's money and cause inflation, causing prices to go up rather than down and prevent people from living on their retirement savings. The gold standard would prevent this.

The devaluation of the Dollar also makes people engage in ponzi finance by investing in housing, causing big booms and busts in the housing market, causing very large business cycles like that of 2008.

With the rise of cryptocurrencies, there has been a lot of interest in using alternative currencies. Allowing alternative currencies could be very beneficial to the American economy but the Government has been unwilling to act on it because of bad advice from the corrupt people in the Federal Reserve.
