First thanks for that tour de force.

To my mind, the mistake is to translate social relations in non-civilized societies into the social relations of civilization. Of course people in non-civilized societies have engaged in swapping goods (and services). There, though, the economy (the production/acquisition of goods/services) has been incidental to other purposes, not a foundational purpose of society. The advent of cities changed everything about human relationships, most especially including all related to the economy (as the very idea of a permanent--ongoing--surplus, which the advent of farming had introduced into the world, was the reason cities came into existence).

It would for sure be a revolutionary economic act to create money without involving debt in any way to fund a guaranteed minimum income for people (at least, one for which any adult citizen could become eligible) and to fund (all) government (forevermore at the current per capita rate of total government spending). That can be done--within the existing economic system, with astonishing outcomes for society as a result.

if curious: "Easy as 1-2-3-4" (a "2 min read" here in Medium with links to more about the proposal)--keeping in mind it is all written, like the article at hand, with the general public in mind
