If you live in a remote enough place that you need your own backup plan then I would think only having to think about electricity would make things easier

Not necessarily. The two times in my life when we had week long power outages, the root cause was an ice storm that brought down trees onto power lines. The ice only lasted a couple days but the damage took longer to repair. Roads were cleared within a couple days. If you live in a remote enough place where your road won’t be cleared shortly after the storm, you need to have a backup plan that doesn’t rely on any outside services.

> which a power outage does not

Things that don't work without electric power:

* Refrigeration. For a 6-12 hour power outage, leaving the doors closed is sufficient. For 1-3 days, fridge temperatures may be maintained by buying bags of ice, but not a freezer.

* Emergency communication. Landline phones might still function, depending on exactly where the breakage occurred. Cell phones have 24-48 hours of battery power at the most.

* Central heating. Even a gas furnace requires electricity for its controller.

* Kitchen ranges (conditional). For a gas range, this depends on whether you have a lighter or matches.

A power outage disrupts normal life. During a power outage, you cannot cook food, cannot preserve food, and cannot heat your home. Depending on the duration, sheltering away from home may be the less disruptive option.

I mean, ideally it should be free to go to a community shelter. If it's not a disaster and just an unfortunate situation, that's what insurance is for. I guess I don't know what a natural disaster would be like where you're from. This is why I live in Japan, where disaster preparedness is taken extremely seriously at a societal level.
