There's definitely some types of situations where people have to "bug out" as in the Fort McMurray fires and the sudden evacuation of 180 000 residents of Mississauga, Ontario in 1979, so there's an argument for being prepared for such eventualities, though there was no significant crime or violence if any associated with those evacuations.
I know of people that had to be ready to suddenly deploy for work purposes that took them into fairly remote areas and a variety of climates, so they had to have gear ready to go on a moment's notice. We've also had opportunities for Red Cross and possibly ARES to deploy on short notice, so I've on occasion found myself adjusting my bags for that.
Lots of us like to camp, sometimes even fish and hunt in the bush, so I regularly pack my gear for that and know many others who do. For a while I had gear sorted in such a way that it would be ready for a couple weeks at a fishing or hunt camp, plus my more condensed camping gear and 72 hr bags, with the idea that I could also use the gear for an extended ARES deployment, etc. I could show up ready to operate for a few days with a BOB and perhaps an extra radio bag, or pack more gear into a vehicle for a longer duration.
Though some of my hunting, shooting and tactical gear could work for some of the dramatic situations spoken about on survival forums, the likelihood of having to conduct a SERE style escape from my home city is miniscule to say the very least. Of course, we don't have anything like a crime ridden American inner city here, but even there I would see it as unlikely.
