Market products such as bonds or fiat currencies also have three phases. It is just that instead of utilization phase, they have the liquidation phase. When a corporation issues a bond, or a bank new units of dollars via loan, this is the creation phase. When the corporation or a borrower put them on the market, the products enter the circulation phase. Finally, when bond maturity date occurs or a borrower makes the loan repayments to the bank, this is the liquidation phase. And the same as with iPhone, it is this phase where the value of a product actually comes from. Namely, in the liquidation phase the bond issuer pays principle to bond holders, while the borrower pays goods and services to dollar holders. What does it mean to pay principle or goods and services. Well, at the beginning of the circulation phase, people invested their money into bonds or goods and services into newly issued dollars. In that way the bond issuer and the borrower received monetary or non-monetary value. For that reason, they have to pay back such value to people who became the holders of bonds or dollars in the circulation phase. The value is paid in the liquidation phase. In this phase the bond issuer pays principle to bond holders, while the borrower pays goods and services to dollar holders to get dollars for the loan payments. In that way, these products are taken out of circulation or in short, they are liquidated, while their last holders received value.
