The present social structure can be thought of as generally hierarchal in nature. At the top, the real medium of exchange is power. (Hypertiger)

A communication theory of exchange lends itself toward a geodetic social structure which is more efficient, and redundant because the information that is actually money travels by the shortest route.

A geodetic social structure distributes control structures out to the hubs where more localized inspection and feedback is enabled.

Esoteric to be sure; but IMO true.
