In Australia SHTF consists largely of environmental disasters - floods, cyclones and bush fires.
The last one, bush fires wiped the town that I grew up in from the face of the earth. Of a town of 800+ people, only a handful of structures remained and 30 people died. You don't need to worry about zombie junkies out to kill your family for drug money. You need to worry about the 50meter wall of flames rolling towards your house like a jet engine. Being immobile would have been a death sentence though if you were at home so she is on the money here.
The hippies and the yuppies suffered just like everyone else though which is a conservative old logging town. The chief of the local fire brigade (a volunteer organisation) had to make the decision to keep fighting the fires where he was or go home to defend his own family. He stayed to defend those in need and lost his wife and child.
I say this not to illustrate that certain people are going to 'get it' when the event happens, quite the opposite. It's peoples natural heroism and selflessness that comes out at these times as people gather together. Rather than the depiction in the video which is basically every man for himself.
Granted, being prepared is critical but that's not what the video is about.
