You did not prove your point that the idea that someone can be completely independent is completely delusional.
Conservatives used to believe in something that Chesterton called "the democracy of the dead", i.e. when we vote or even just going about our day we should keep in mind the sacrifices of those that went before us.
Obviously prepping, and doing so with the latest/greatest knowledge and technology (and good old fashioned knowhow as well) is a great thing.

But some of this SHTF stuff comes way too close to libertarian hyper-individualism which is ultimately wrongheaded and self-destructive.
There were a lot of independently minded people living in Colorado in the 90's who just went about their business while thousands of Californians moved in and turned the state purple.
