Where would the government get enough gold to back all our fiat dollars?

How much gold would that be?

Good question. The government has 8,000+ tons but some people question whether they really have it.

The FED has added a couple of trillion dollars with QEx.

IIRC we (the USA) would need about 20% of all gold ever mined to make the gold standard work again.
