At this point, all alternative economic thought is welcome. If nothing else, should the addiction to growth continue civilization will collapse and new ideas will be definitely be needed for the scattered human communities that will then exist.

I have developed a macroeconomic alternative that I thought anyone reading this article might find interesting. It, too, references an old idea: 'neutral money'--and Keynes.

This proposal ties total output to demographics by having demographics determine how much money (as currency) will be supplied to the economy, in the form of a guaranteed minimum income and public spending. (The necessity for a mechanism to retrieve monetary from the economy is realized.)

if curious: "'Neutral Money'" (here in Medium, but not behind the paywall)

William Adeleke and I have been brainstorming ways to create a scrip for local communities that would supplement a national currency. We have devised a two-tier scrip. It would be issued to all (adult) individuals monthly, to expire at the end of each month. People accepting the scrip in exchange for goods/services could exchange it for scrip that would expire in, say one year. Again, this would not replace or even compete with the national currency, but would be a way to supplement it for locally produced goods and services. In the Ekhilur Project the 'local community' could be the network.
