> I always found the prepper mindset a little curious. It seems to me that any kind of major disaster that would totally knock out reliable access to food and aid for 3-6 months (i.e. something worse than the recent hurricanes, more along the lines of climate-change-driven famine apocalypse) will also probably have knocked it out for far longer than that. What happens when one runs out of one's few months of stockpiles?
I would expect that the world would go through several stages after such a disaster:
1. Disaster happens that destroys normal food production and distribution over much of the world.
2. Widespread violence breaks out as people realize help will not be coming and starting fighting over resources.
3. After a couple of months, the fighting and starvation have greatly reduced the population. Most who have survived are weak and out of ammo for firearms.
4. Those who had 6 month stockpiles and were able to keep them (either by being somewhere away from the violence, or by having sufficient arms to defend them) come out and start working with similarly prepared people to get farming going again in their area. They are in good health and have ammo for firearms and so can deal with any survivors of stage 3 who want to try to steal from them.
I don't think the goal when preparing for this kind of disaster is to live off your stockpile until civilization is back to normal--that would take way more than 6 months. I think it is to live off the stockpile until things stabilize and we have enough regional civilization to enable seriously working on rebuilding.
