For example, in the United States, the dollar was defined by the Coinage Act of 1792 as 325.25 grains of silver. There is no definition, i.e., there are no units of measure. This lack of a defined unit of measure, as postulated by then Warden of the Mint Sir Isaac Newton, was enough to preclude the use of fiat money in England in the year 1700 and for almost 230 years thereafter. The amount of money is limited by the costs of producing it. Because fiat money is created without work, there is no limit as to how much can be created.
People recognize commodity money as something that has intrinsic value.
This has been true all over the world for all recorded time. Because of material misrepresentation and nondisclosure about fiat money, people are tricked into accepting and saving it. In addition, legal tender laws coerce people to accept it when disputes are adjudicated in the courts. The U.S. Constitution implicitly disallows the notion of fiat currency in Article I Sections 8 and 10. Honesty in business dealings is considered consistent with holiness and with moral law.
