While I live the same way you describe, I have heard a different take on availability of food supplies.
The multiple loads to the supermarket each day are for fresh foods: dairy, produce and bread. The on hand supplies for canned/packaged/dried foods is a couple of weeks. In just my rural area, there are 4-5 different warehouses for shelf stable foods. Each one holds perhaps one month’s supply. I know quality assurance people who work for the processors. They also have stores of processed food, again, perhaps 1+ month if they had to supply all the populace in a given area. I do grant this is an underpopulated area, so if there are fewer warehouses in densely populated areas, that makes a difference. Those warehouses are the target for confiscation and will be defended, in some instances. Farms will also be subject to inventory and the government will likely offer *compensation* for what they confiscate. It will not be market value in a shortage, however. There will be price controls and penalties for overcharging. There will be limits by the government put on stores on hand,
Most of our local truckers go home at night. They have routes that can be covered in a working day. Besides farm diesel, there are government fuel depots. If there are hunger riots, this fuel will be allocated to transport food to places of unrest, along with military security guards.
The government itself is telling people to have supplies on hand. Each prepared person is that much less of a drain on the *public* resources.
It will be bad, I don’t disagree. But it will be bad in a different way from what is commonly described.
