" We can easily imagine a monetary organization which, by the exclusive use of notes or clearing-house methods, allows all transfers to be made with the instrumentality of sums of money that never change their position in space.

If differences due to the geographical position of money are disregarded in this way, we get the following law for the exchange-ratio between money and other economic goods: every economic good, that is ready for consumption (in the sense in which that phrase is usually understood in commerce and technology), has a subjective use-value qua consumption good at the place where it is and qua production good at those places to which it may be brought for consumption. "

― Ludwig von Mises , The Theory of Money and Credit
