Money, accounting and cities

I would think they go together.  Cities comprise the rise of shops,specialized tradesmen.  They take inputs and deliver outputs, no public flea market; it is a city.

Early skilled shops would take a raw material for production of a specific sort, and keep account of the raw material.  In the general case, the customer delivered the raw material, and the produced output was pre-assigned in the traders book.

From there we have the simple matter of one customer re-assigning the delivery for a future product, money.  Sovereigns, naturally, would impose a share of output from all craftmen, keep the sovereign's mark in each book.

We had paper, we would not start with a commodity. Real commodity money is jewelry, still exists and dates back to bartering and stone age.
