So preparing for one thing makes no sense. Either you prepare for everything, or you don't prepare.
Bluntly put, this is nonsense. Everyone has a budget. Everyone has an idea of what is likely and even if the unlikely happens, what can be done about it.
For instance, an EMP event would be crippling. Maybe you think you can sit in your shelter with your six month food supply, but what then?
You got a horse, seed, 40 acres, and a plow?
I don't care if you were prescient enough to afford a 1960s or earlier car. You won't be getting gasoline to run it for years after. Not if the EMP event is really crippling (and designed to be by our enemy, whomever that is).
I hope you have some sort of independent source of heat because you aren't getting coal, fuel oil, or natural gas, either.
To be really prepped for an EMP event of sufficient severity is to basically replicate the entirely 19th century farmer lifestyle indefinitely. All ahead of time.
Or, you could admit you haven't the budget or the skill for that and make an economic decision to prep for something lesser.
Me, I don't care what you do or don't do. It's a free country. Do what you think best. But, there are events that are well beyond "prepping" or for which "prepping" requires, taken seriously, a scale of preparation that amounts to an entirely different life, one for which you would redundantly pay for, physical "plant, property taxes and all. I don't think most of us are up for that. But, we might decide we
could be ready for lesser events -- extended outages due to natural disaster, perhaps.
Or, you could assume that the enemy is kind or somehow, it only takes three or six months to scrounge together a power grid and a transportation system after such a thing. That, too, would limit the prepper budget.
But to prepare for a dark ages level event -- that is
really substantial. And far beyond what I have heard most "preppers" ever discuss.
