Without modern technology and the fantastically complex supply chain that allows the farmer to put in, maintain, harvest, and distribute his crop he's just a guy looking out over a weedy expanse. As part of a global economy he can feed tens of thousands, after "collapse" he will struggle to feed his own family for long. Your chicken, my chickens might stay in the coup (mine free range in my backyard) but we are outliers. The vast majority of people in the industrial nations provide 0% of the food they eat.

I responded to your attempt to describe the effects of "system failure" where you correctly point out that in that event money would become "pieces of paper"...very true but hugely incomplete. When Covid put a small crimp in the global supply chain the supermarket shelves emptied in days, after a "collapse" they would never refill and hungry people would swarm both of our yards in search of chickens.

Nowhere do I assert that capitalism is "the end all be all", nor do I characterize it in any way. There may be different ways to produce and distribute goods and services to the world's 7 billion people, right

now they don't exist. If you believe that you "don't need the market of any kind to survive" then in my opinion you are failing to realistically observe the world around you and your place in it. Possibly you can live solely on the products of your property with no outside contribution, if so you are one out of many millions and after a "collapse" they will be casting hungry glances your way.
