How big are your food reserves that you have on hand right now? One year? Two years? Ten years?

You don't tell your neighbors about it, do you? They might say, "Oh, I don't need to store any food. I'll just go over to cx01's house and eat his food."
What would your neighbors think if you told them in advance that they couldn't have any of your food, that you personally sacrificed for in the form of opportunity cost? Would they think that you're not very neighborly? When the National Guard comes around to collect all of your stored food so that it can be distributed equally among your neighbors, are you planning on handing it over peacefully?

Paul James, 85, standing beside some 200 cases of Mountain House freeze dried food. Purchased and trucked all the way cross country from Oregon in 1975, this "mountain" of food was recently pulled down from where it was stored for 37 years. [...] The year was 1975. At that time many Americans were concerned that the Cold War with Russia could turn hot. People all over the country were building bomb shelters in their backyards and storing large quantities of food.
I was one of them. I didn’t build a shelter, but I did order $10,000 worth of Mountain House freeze dried food
Personally I don't keep reserves because there's no risk of war (at least I think so). If there was war and I had reserves, then libertarian ethics would allow me to defend my reserves (with force).
The nation that does not prepare for war, is at risk for war. If you personally do not have any food stored, and you and I live in the same nation, it puts me personally at risk of war.
Massive French government fortification program designed to protect their borders with Germany and Italy.
France knew perfectly well that the Germans were a clear and present danger. They just could not do anything about it - despite having that great protector: government military.
