You've heard of Preppers, right? People who spend a lot of time (and money) getting ready for TEOTWAWKI, otherwise known as The end of the world as we know it or at least a natural disaster of great scope and scale. Think of an EMP (electro-magnetic pulse), (here's an article to scare you), a meteor striking the earth or at least a hurricane or tornado. Books have been written on the topic, for example, One Second After, Death of Grass or Lucifer's Hammer. I watched a show on Netflix about a family that gone to extreme lengths to be self-sufficient with back up systems for off the grid living. The husband, an engineer, knew what he was talking about and revelled in describing what they had been able to do. They raised cattle, had their own water and energy systems, complete with generators, tractors and solar panels. The wife focussed on the domestic end with a large storage space and professional grade canner enabling her to put up 15 years worth of food.
The fellow was proud of his accomplishments and had bragged to his neighbours and friends at the local pub. They in turn had let him know that they would be looking to him should a world disaster strike. He had no qualms in telling them to basically forget it; he was not going to take food out of his child's mouth to give to them. I guess they didn't buy him a beer.
Maybe it was because I have read the books listed above but I immediately thought, "Foolish man, you're the first place people who haven't prepped will go to take from you what they haven't done themselves." Sure, he had a gun collection and would be able to take care of the first few of the hundreds of the desperate starving masses but he wouldn't be able to hold them off for long. Actually, he'd be better off to invite his neighbours and friends to join him and create some safety in numbers. He seemed to have enough to share.
Another likely scenario would be government confiscation of his carefully accumulated security. In World War II they dealt with what was labelled hoarders who were widely castigated for not sharing.

I wonder if the prepper's knowledge and skill amply demonstrated in the setting up of his homestead is really his family's most valuable asset. Most people wouldn't know where to start.
