The problem with the FED, and every Keynesian economist is that they think the US will indefinitely be the world currency reserve, and that 5,000 years of gold based monetary policy is less stable than the post war economics that have given us rising inequality, lowering employment, indefinite QE, China calling for a de-Americanized world, and an interest rate ceiling of 1% (look it up, Bernanke said it!) that was the bottom rate of Greenspan.
I just love when current economists tell me I'm naive, and that government debt isn't the same a debt debt... Or that there isn't a borrowing limit. The limit, is when other governments stop buying your currency. See China-Australia trading deal, China's ease on buying bonds, and look up an interesting theory on how Japan will soon stop buying US bonds, due to it's self-inflicted inflationary policy, which will force it do invest in it's own money supply soon.
