not sure what you're saying, that you can only imagine support networks in societies through this current system - seems like both a limit of the imagination and a lack of looking at where that's been demonstrated (in likewise post agriculture, large scale society). I didn't elaborate in my OP on solutions, I only offered some ways of evaluating how healthy/"advanced" a society is (not just looking at individual potential)
Imagination of some future utopia is a dime a dozen. Scenarios that actually work are much less easy to find.
>in likewise post agriculture, large scale society
I don't see any post agriculture "large scale society". I see an even more increased role of agriculture, amidst food and resource wars, and society dropping in numbers (and scattering to smaller dwellings), what with climate change, and all.
