Thank you. Now I understand that concept and provided feedback.

On this case is different because each living person is their treasury that can issue bonds for their own currency, which on this case is time.

So in theory one person can issue thousands of hours in debt. The question is if the market (buyers) will see value in accepting those hours (bonds) and if the issuer (person) is deemed as capable enough to pay the debts (work on behalf of the bond owner).
