The author shows that before there was money, there was debt. For 5,000 years humans have lived in societies divided into debtors and creditors. For 5,000 years debt and debt forgiveness have been at the center of political debates, laws and religions. The words “guilt,” “sin,” and “redemption” come from ancient debates about debt. These terms and the ideas of debt shape our most basic ideas of right and wrong. source
You can't describe how various forms of monetary value work in the modern monetary system as if it were a rural village with physical items, because it is fundamentally different.
In those periods, people work more on credits and debts, which shade directly into systems of social obligation and caste when extended over time.
(As you note) It's also very historically recent that 'making money' was seen as any kind of reasonable choice for someone with power. The political and merchant classes are typically quite separate (the exceptions prove the rule); the merchants are picking up an under-explored source of power that is mostly uninteresting to the the ruling class.
Some books I’ve liked recently or that are all-time favorites: Crime and Punishment by Fyodor Dostoevsky, Debt by David Graeber, and The Anatomy of a Moment by Javier Cercas.
