I just copied your list to Word, deleted the items that are completed or not applicable, and looked at what was left. 24 items left - much more manageable.
Next I listed ten easy fix items (Duct Tape, Salt, Vitamins, Extra Batteries, A Fire Extinguisher, A Map Of Your Area, etc.) that I want or want more of, wrote them down, and put them in my wallet. Within a week, I’ll be down to 14 items. That’s even more manageable. At that point, I can consider them one by one, and either work on them, dismiss them, or plan when to start on them. (No, I don’t have “several years” of food stored, but that strikes me as over the top unless everything else is perfect.)
My basic plan: Be able to stay in my home with my family, even if things go badly. Be able to protect my home against reasonable threats. Outlast perhaps a few weeks of total chaos, where government is part of the problem, followed by perhaps a few months of risk from two-legged predators. Then help to rebuild America as a free country.
I have done well with the list and much more.
Your basic plan is Not for as long a time as I believe I will have to take care of myself...
We will all need LUCK as well as planning, or is it LUCK because of our planning?
