Where does MONEY come from?
Who creates it?
Congress, by unconstitutional means.
At any rate, in the context of this thread, I was just opining that "keystone" is a reference to the Federal Reserve / Treasury.
And yep, money comes from thin air. Nothing wrong with that in principle, as long as the creation and destruction is done in proportion to the needs of commerce, and the "money market" is transparent to the public.
