I have a theory. When Q states that gold will end the FED I think that's a brief overview. The US is on track if not already the largest oil producer this means there would no longer be any necessity for OPEC with Saudi Arabia to exist as the US will be self-sufficient. If OPEC is scuttled I'd imagine the Petro-dollar goes with it. This would mean the US would switch to a gold backed currency like in the past. This would effectively nullify and subsequently collapse the FED.
