decided to do some research on a world without stock markets, maybe these articles would be useful to FA's world, which bans making money from money
https://www.linkedin.com/pulse/what-stocks-didnt-exist-john-m-paul-aif- this deals with the history of investing and argues futures markets would exist even without a stock market
https://www.thebalancemoney.com/what-if-the-stock-market-didn-t-exist-2637105 this is a capitalist argument for the stock market but may detail potential issues to be worked around (low key hilarious that it laments the loss of walmart in such a world)
https://www.physicsforums.com/threads/what-if-there-was-no-stock-market.260638/ a forum debate about the stock market which mentions alternative financial systems. alludes to the public goods game (libraries) and co-ops in a lot of ways.
https://www.theguardian.com/sustainable-business/stock-markets-no-longer-fit-purpose this points out the flaws in the stock market and also mentions a field guide to regenerative economies, though said field guide was created by something called "The Capital Institute", so idk http://fieldguide.capitalinstitute.org/evergreen-direct-investing.html
this describes a market socialist economy that may be a stepping stone to FA's communism or a satisfactory state on its own (assuming proper governance mechanisms) https://www.reddit.com/r/SocialDemocracy/comments/olqi4a/are_there_economic_problems_with_locally_owned/
