Articles about individuals' backup plans for catastrophic collapse of civilization do tend to crop up every now and then; this isn't the first one I've seen.

I think one of the key fallacies that goes on in these circles is that people don't really think through what a catastrophic collapse of civilization looks like. A 2000-mile drive is quite a long trek to take, and attempting it in a post-apocalyptic scenario requires a lot of planning (for example, what are you planning to do for gas, food, rest?). A diesel generator is a lousy power supply in the apocalypse, because diesel is a resource that is going to run out quickly and need to be procured.

For these luxury bunkers, I suspect some of the demand is because they look like assets that might be easier to hide from nosy people like the taxman.
