@icedquinn Well Marx did write Das Capital.
Yeah, it's called opportunity cost if I'm not mistaken, except capitalists don't frame it like evil troglodites.
There is cost to running the mess halls and that cost would add up to the cost of the food which depending on your situation could be more than if you didn't work and prepared it yourself. Which would mean you would try to kick in economies of scale to lower the costs, however that would create a gigantic point of failure and also the food would be shit and unhealthy which demoralizes and lowers productivity. He would probably say the messhall should be free but then he's just putting his unpaid labor onto someone else.
There is also opportunity cost in waiting for the communal kitchen to become available.
@icedquinn I feel like my reply already addresses that
@icedquinn I feel like that's just reinventing the wheel (money) but increasing the administrative overhead
@icedquinn Oven is a bad example because it's cheap and useful but it could probably work with kitchen robots and their various attachments etc as you don't usually use those for your daily meal.
we kinda used to do that. have longhouses where the tribe eats dinners etc.
