This strikes me as a rather strange way of looking at it.
The only way there's nothing I can do about it is if I'm dead or seriously injured, and in that case there really is nothing I can do about it, so why worry? :-)
The shift from "there's no Internet/food/water" to "let's start making progress toward resolving this" is easy to make in that moment, and there are plenty of people who have the skills and patience to make it happen. It might take longer than we all might like, but that's fine. As long as we're alive, there's always something to work toward, and always the ability to make some progress.
The internet failing kinda sucks, but thats what a charged kindle is for.
I don't know about you, but for me the vast majority of possible disaster situations would not include fleeing my home and city.
Local disaster (e.g. fire) would flee my home but use city services. Regional disaster (e.g. blizzard, civil unrest) would involve staying at home for the protection / amenities it provides.
Personally, I think fleeing to the wilderness is an anti-pattern and I have not seen a situation for me that would necessitate it besides the end of the world as we know it (e.g. nuclear war), but IMO that moves into "some prepper crap" territory.
If you live in a region with seismic activity, earthquake preparedness might necessitate a bugout bag, but that's hardly 'everyone'.
Civil Unrest/War can also lead to folks fleeing their homes- see the massive numbers of refugees fleeing warzones. Staying in your home in such a situation may not be the wisest course of action.
Earthquakes as you mentioned can be another cause- also, tornados- but tornadoes are usually fairly localized.
I don't know how many of the other ones realistically call for a bugout bag. Big storms have days advance warning - you don't need to be ready to leave at a moments notice, you need to decide days beforehand whether you're evacuating or boarding up your windows. Most civil unrest does not warrant evacuation in the United States, and if it got to that point, it would probably not be a sudden and unexpected departure.
Maybe I should clarify: In my previous post I wasn't so much against the idea that someone should need to possibly evacuate, as that you need to prepare to make a sudden and unexpected evacuation from society as a whole (like a "take the bugout bag and make a run to the woods" situation)
As for big storms- ideally, yeah, but it seems that a lot of folks try to ride it out, it ends up being worse than they expected, they get flooded out, and now have to be evacuated in a hurry.
Food in the supermarket, water, telephone service...
And imagine that they go away and there's nothing you can do about it. No-one to complain to. What do you even do?
Yes, obviously Internet isn't the worst of the set to lose. But it's a way in to thinking about the feeling that something you've utterly relied on can just ... stop.
