good idea might be separate dry toilets for sick and healthy people... in the case
of failure
of crops (finnish still has just one word for this «kato») there should be some sort
of transport system still present (priority on humanitarian purposes), when everything's in reasonable state this can be used for spreading
essential industrial products like communication tech, spare
parts for farming machinery, biodegradable materials, I'm not sure what an optimal size for such a utopian community would be, but there would have to be some electricians, repairmen for machinery, maintenance
crews, communications experts, well your typical 1930s top craftsmen with a dose
of tech experts from the 1980s and 1990s.
