Good work Menger

On the Origins of Money.  I buy the argument, and go further, this guy understood channel theory as I read his text.
One point, the flow of money or deposits, whether fiat or metal, moves toward near coherency with the flow of other goods it is traded with.  In polynomial space we might say that money, at equilibrium, has a bounded function that is a multiple of the unique prime functions that comprise other goods flow.  It is near synchronous at every point, hence the need for low transaction costs when moving money about.
