Even if we assume that the Fed is not a nefarious (which it is), the temptations of being able to create money from nothing are tremendous.
If the Fed is to be reigned in (it is unlikely that we could actually abolish the central banking system), then there needs to be systematic limits on their ability to lend money.
One way to do this would be to eliminate the trade deficit, which creates demand for USD via the balance of payments. This is how the Fed was limited during the Bretton Woods system.
I have been to Ecuador and people are very pleased with the change to the dollar.
One of the things Trump has talked about is bench-marking the US dollar to a crypo currency. That would stop a lot of the Federal Reserve Bank QE and other nonsense and allow Congress to control fiscal policy rather than the Fed.
