Value is generated by work, but valorization is based on processes of use or exchange. Generally assets have intrinsic value. Fiat currency has no intrinsic value. Its value derives from the state assuring a demand for goods and labor, which will be purchased in the currency, from assuring the availability of investment assets, which will promise a return above an original value, and from regulating the supply, to assure that the values of ordinary goods will remain generally stable.
