Sound money is the equivalent of scientific integrity, the system must not permit the manipulation of data after the experiment has taken place. Manipulating the value of money is the equivalent of manipulating the data of a scientific experiment after it takes place, distorting the information economic actors need to create new wealth. Money carries the information to investors, workers, small businessmen, major corporations and entrepreneurs. All need to gauge the success or failure of their attempts at growth. Money cannot be expanded or contracted at the will of the sovereign. In order to explain a willingness to exchange real goods and services for it, money must be strictly limited in quantity. Sound management of money cannot focus on finding stable elements among existing goods and services that are endlessly multifarious and changing. These very changes are what money must measure.
