I think this is a bad idea. It is effectively what the US government is doing with the current zero interest rate policy. Right now interest rates are basically/effectively zero. They should be 4-10% (my guess at a long term 500 year average with no government intervention). Inflation causes the US dollar to lose money each year. So While you can hold cash or put money in the bank annual inflation -lets call it 3%- causes the US dollar to lose value. So right now putting money in the bank you lose 3% to inflation and 4-10% -lets call it 5% interest you should have earned so 8% a year cost of holding cash. Bitcoin and the cryptocurrencies were created by people who were not happy with government banking policies. Most people would not object to a dollar backed crypto-currency. The best way to do that would be to have a central trusted bank issue it; but the the government has shut down those attempts (and there are a lot).
