Were you the one who posted the first thread from that website?
To a couple of the points you brought up:
The author put in an addendum at the bottom of that article that addressed people’s disagreement with his “One-Hour” timetable. He reiterates that it’s just an opinion, and that the total breakdown could take anywhere from an hour, up to a month to fully play out.
Personally, I agree with his initial assessment. Our world is so inextricably interconnected (especially the financial system), that if all of the major financial institutions shut down at once, it would cause instant panic, mayhem, and chaos all across the developed world. I see that as totally plausible.
As far as cash is concerned, I doubt that it would be worth much of anything, once everything crashed. At least not at first. The worst of the death and destruction would have to pass before the survivors were willing to begin doing any sort of primitive commerce with each other again. And at that point, I’ll bet that paper money wouldn’t be a recognized exchange medium. I’m pretty sure it would be precious metals. And even that wouldn’t happen until after things had stabilized quite a bit. Initially, barter would be the standard order of business.
Don’t know that I’d rely too much on the neighbors, either, unless they were as prepared as you are, and wouldn’t resort to trying to kill you to get your food.
Like the author says, being situated in a rural, or even semi-rural area will be the best possible place to survive such a disaster. If you’re inside a big city when the SHTF, you’re almost certainly going to be toast, unless you’re heavily armed, and have some way of making your way out without getting killed.
A while back I had posted a thread relating to shelf life of canned goods, part of which came from his site.
Tell ya what, though, I just read his recommended list of a years supply of food, and it seems to me he is way over. But who knows? I know my appetite and food habits easily double if I’m doing things that take alot of physical activity versus sitting on the couch.
