Besides all this, consolidation and integration of life-support is the way of the future. If you look at society as one big system, it makes a lot of sense to have lots of redundant units rather than all units depending on one central resource. Sole and batteries for example harden the whole country against equipment failure, terror attack, negligence and natural disasters. With a single power plant any instance of one of those things could bring down huge numbers of houses. Technology is making it possible to produce some of the things you need in home, so there is a funny convergence of preppers and technologists.
His comment not only is ignoring real-life examples that have happened within his life time (Afghanistan, Iraq, Syria, Venezula, Katrina, Puerto Rico, etc.), he's also postulating that these new governmental structures would magically spring up over night, rather than taking years or even decades to emerge.
I'm no prepper, but I do feel that I am knowingly taking a risk, albeit a very small one, by not being one. If I had a family to care for, I would definitely be more prepared with 3 months food and some emergency medical supplies beyond a first aid kit. It's a small enough risk that it will probably not happen for my generation or my country, but it does happen.
I also often don't buy insurance for things I think aren't worth it, but it's still a deliberate choice rather than sleep walking into it.
It's almost on the same risk percentage as Home Insurance, so if you're insuring your home, why aren't you 'spending' a little time each year prepping? Just because it's socially unacceptable, but home insurance is regarded as socially acceptable?
I agree with the parent -- it's just insurance, and is a cost-benefit trade-off that needs to be evaluated in a similar fashion as flood insurance or the like.
There are a lot of what I'd call "psychological" or perception-based factors for doing things like hoarding guns and food, and it's easy to go overboard, but they're not fundamentally poor choices.
If that infection had a happened and I couldn't get antibiotics, clean water, food, shelter, etc. for a month things could have gone quite the way south.
You don't need to survive Mad Max style for decades, you just need to make it a month or two until roads are open and power is back on. In this case having a stash of antibiotics could mean the difference between life and death for someone that's injured, and as the article points out there's no real good reason to grow your own when you can buy serviceable alternatives online.
