Money is just a commodity like cans of beans. Money is only used as a primary means of trade because the other means were taxed out of existence by western governments to allow for the rule of the central bankers.

For example, before private bank notes and barter transactions were taxed, most people traded in private bank notes, mixed metals, furs, beads, etc. Central bank / government currencies were rarely used. That you focus on central bank money as a trading medium better reflects your knowledge of history than economics.
