One would hope that the Fed wouldn't actually allow that to happen. But how does one re-impose reserve requirements without causing even more problems?
It's like in that one song: "And I don't know why she swallowed the fly. Perhaps she'll die."
On the upside, I suppose we'll now get to have an empirical test to settle that age old debate over whether the number of people allowed to print money should be one or many. Pity Bitcoin's in such a shambles, so we can't with clean conscience make it a test among zero, one and many.
