In the same scenario in other countries, it's after the Gov nationalized food warehouses, distribution center, and that's after they nationalized farms and food co-ops.
Google "willing-buyer-willing-seller" policy. Scary turn of event.
PS in most scenarios, the big GOV did not have to come after you either, by then, hyper inflation set in and neighbor turns against neighbor. The local LE then will confiscate your food/asset in the name of peace.
