It's symptomatic of the economic way of thinking, in terms of game theory and systems that have emerged more or less out of nowhere. Explanation beyond the surface level of transfers of money is relegated to the work of economic historians. The way mainstream economics focuses on "shadow forms" (as Patrick Murray put it) purposefully excludes the supersensible movements below the forms of appearance of money, capital, labour, interest, rent, etc.
