Survivalism is a collection of absurd delusions.
You have your own solar panels, your own water supply, and your own food growing and preserved on your own property?
Someone bigger, stronger, or better armed can steal them, enslave you, or kill you and your family.
Arm yourself? Sooner or later, your weapons break, you run out of ammo, or someone with better guns overwhelms you.
This species did not evolve in isolated families, but in clans and tribes. Practically speaking, there is no such thing as individual survival.
We survive together, or not at all.
