My purpose is to motivate a few people who have done nothing at all to do Something, no matter how modest, to help themselves before-the-fact. Now you can ridicule, dismiss, and disparage all you like, and point out by inference how minimalist these four points are, but have some consideration for those who have postponed and procrastinated because the job as the experts define it, it too big and expensive. You would serve these people better by contributing something positive as opposed to sniping.
First steps are followed by second steps — but only if first steps are taken at all.
And for many moderate and mild situations, the first steps can make a huge and adequate difference. I grew up on the Oregon Coast, and one could expect that every few years there would be a storm that would take out power for multiple days. All the steps outlined seem like second nature, and they suffice.
I now try to be 3-6 months ahead of the curve (though ideally about 18 months with regards to heat—I’m in Canada), and figure that simply surviving that long will be a very good leg up on most people if the worst does happen, and trust that God will provide.
