food commodity trading? idk sounds speculative and ignoble to me, probably don’t need it - more money for the artists!
Some things need funding despite being unprofitable. Not everyone will agree, but I believe art/culture (including often unprofitable forms thereof) are worthwhile, and should thus receive public funding (to some degree). I believe the same about justice, policing, education, research etc.
None of this rules allowing a freeish market to operate where doing so "delivers the goods".
art is relatively low on my list of positive externality activities to subsidize, after stuff like ensuring everyone has food to eat, home, etc. at least in the US, we are already running a deficit so we do not even have the money to do this - let alone some broad UBI for artists.
and how do we agree on what jobs are undercompensated? every person will have their own hobbyhorse
What would also be much more valuable than creating art is making that art available to everyone including for the purposes of producing more art. If the art subsidies came with a condition to release the art to the public domain then I would be much more for domain-specific funding.
