I'm interested in your third paragraph, particularly "Money demand comes from things like tax codes, debt/bankruptcy laws, torts, ...civil fines, etc."

In prison, packs of cigarettes are money and none of the things you mentioned exist. Yet in a prison I can trade a pack of smokes for a tattoo, drugs, cellphones, etc. It seems like money arises out of the need to have a reliable, constant value for exchanging good and services.

Do you differentiate between money and currency(medium of exchange)?
