it's very hard work to manage livestock and vegetables to feed yourself self sustaining. you need a family to manage such an operation and if your animals get sick or bad weather then you can starve. it takes about an acer of gardens to feed one person year round. of course this can be diminished and supplemented with livestock and hunting. then that makes your new job a farmer and or hunter gatherer.  people would rather work a comfy job in civilization and skip those steps. you buy your food prepacked at the supermarket and can even order it pre cooked and pre made. so the question is why even bother going off grid in the first place.
