Hobbyist activities are a good way to start, but you would need some specialization for this to take off. Using food as an example, if everyone is: -growing a bunch of different vegetables/spices and -milking a cow/goat and -collecting eggs -etc. for only their immediate family, it is very inefficient. If every family in a group of 5-15 families had their own productive activity that was a time commitment of 5 hours (max) a week, a ton could get done. Focus should be on items the market produces ineffectively/inefficiently: -proper pickles -sauerkraut -raw milk -Kefir -free range eggs These things are all scarce/overpriced in a supermarket. Even in a wagecuck lifestyle you have time to produce one of these. Trading is not strictly required, as long as you are paying each-other in cash to avoid taxes you are fine.
