Money can be issued only in the act of buying, and can be backed only in the act of selling. Any buyer who is also a seller is qualified to be a money issuer. Government, because it is not and should not be a seller, is not qualified to be a money issuer.
Political economy is a fiction. Economy can have but one sphere, namely, in the practice of the individual. Political economy implies that the state can have a separate existance as a creative force, whereas, it is but one of the instruments of the individual's economy. All wealth - all economic planning - can spring only from the individual for his private guidance; and in him resides both the political and economic power. The ballot is his instrument of political power; money his instrument of economic power and the former is futile without the latter. He is a dupe, who believes that government can be both his servant and his patron, i.e., that the state can develop an economy to enrich him. He must govern government as he governs himself; and he must provide for government as he provides for himself. Any power existing outside himself is only that which has been delegated by him, or has escaped from him; for he is the one and only power-house. He cannot delegate his money power, if he would, because it is inseparably linked to his buying wherein he must exert his private discretion. To issue money, one must buy, to buy, one must appraise. Hence, the money issuing power is undelegatable and unusurpable.
When man has mastered money he shall have mastered not only his economic problem of prosperity but also his political problem, for he will see that money has no place in state functions, and, the money power being entirely in his own hands, he will easily master the state and clearly define its services. Thus money must be seen as the means of mastery of all economic and political problems. Until we have mastered money we shall not master any of our problems. Not money, but a false money system, is the root of all evil.
