You completely missed the author's purpose here. He's not espousing socialism, he's preparing to have the extra supplies on hand to pay for a protection squad, and the means to arm them as well. I'd wager this guy would be around and kicking long after the short-sighted lone wolf types had fallen.
I’m guessing that the Korean shopkeepers in Los Angeles were passing out firearms left-and-right during the riots and not worrying about your skill level.
LOL Id wager a smart prepper isnt going to be a lone wolf nor will he be short sighted. And this guy you refer to having stored all those supplies and guns then giving them to his neighbors will be turned on by those neighbors who now have all the guns and supplies and no longer need him using up any of them.
Keep thinking outside the box and look for anything that interests you that you can do. Youre never to old to learn something. My grandfather was still carving wood in the nursing home at 92.
