I knew someone who became a “survivalist” in the sense of (legally, mind you) stockpiling firearms and ammunition.
However, he did all of this in a traditional wood-frame house, located near several trees.
I told him, look buddy, do you really think your enemies will line up one-by-one and come at you straight-on so that you can pick them off?
Doubtful. They will probably just torch everything around you and then torch you out of your own wooden house.
That made him think.
But I think it’s a very overlooked aspect of “survivalism.”
Also, the lesson from various wars and insurgencies around the world is that one single dude cannot protect an entire perimeter, especially not all the time. You need many people in your compound to defend every side and every approach. Singular dudes who try to hold down forts may have a lot of weaponry, but they invariably end up dead.
