it's a class marker, and a real one.
the monty python scene is funny and everything, and i posed it because it's a great satire regarding what people are imagining a system like this would actually be.
but, what a food production system based on permaculture would actually look like, and fairly quickly, is either functional or literal feudalism, as the wealthy buy up the farms (after fucking with the system to force the farmers to sell) and reduce the farmers to serfs.
if you're really rich, that might sound great.
but, if you're concerned about sustainability from a working class perspective, there's no future in this and it's just a waste of time bothering with it.
