The Fed uses interest rates, reserve ratios and open market operations to
manipulate the money supply. There's $3 trillion dollars in the American Economy right now that was printed by the Fed. There's $50 trillion dollars worth of debt created by banks. The Fed isn't "shutting down" anything for any long duration of time. Who are you fooling? Our entire way of life is predicated on easy and undisturbed access to large amounts of debt (again, $50 trillion dollars worth)
bringing the entire thing back full circle
