Sounds good but I have my doubts. Usually, you can't beat specialization. Now people are outsourcing their clothes washing, their clothes drying, their ironing, even people who cook at home want the ingredients to arrive at their home at the precise quantities and with clear instructions on how to make them into a meal with the exact macronutrients they need. I somehow doubt that growing our own food will be cheaper and more efficient than someone else doing it for us. If there's inflation or other issues, maybe there's better ways to deal with them, cos we're in a really sad state if we need to start growing our own food and buying our own chickens in order to survive.
