If society collapses, your soft skills, knowledge and tactile skills/talents will be what gets you food.
You better have something to offer the horde that shows up to your doorstep. If you don't think they won't have guns and ammo and outnumber you, you're kidding yourself.
I tend to believe the whole society collapsing idea is pretty far fetched. If you want to prep for disaster, have at it. But thinking society will completely degree on a dime like that just isn't a productive use of your time and mental energy.
