You’d have to come out eventually.
Just watched it on Netflix! Sad, but great acting!
“You’d have to come out eventually.”
You have to understand the mindset. The folks who get these things believe that there will be some sort of “cleansing event” and that the bunker will insulate them from the harsh transition.
The thinking is that the year or so gives plenty of time for the “die-off” to occur, and they’ll emerge in a much less daunting world.
Maybe they are crazy, but to them, having the option is better than not having the option. There are obvious issues to contend with - including psychological ones that would crop up over time.
The point is that it IS possible to build a multi-hazard cocoon within which you can be protected from whatever you are worried about. It can be done clandestinely, if you are clever and you need not be helpless in the event that someone finds your “bunker”.
