Not a great idea because it would only be a temporary fix until the end of this fiscal year, but. The authors make a big asumption that is likely incorrect. The US no longer has 8,000 tons of gold. They leased it out  surreptitiously decades ago. They couldn’t sell and announce it publically like Canada and the UK did, because the US is the global reserve currency, but it is long gone. If not, some past administration would probably have done what the authors suggest and revalued their gold holdings.                                                https://www.zerohedge.com/political/fixing-debt-ceiling-crisis-gold
