I sincerely hope you don't resort to using your oven as a space heater. That is a very good way to die, usually by CO poisoning. Dress warmly and bundle up in layers. That is what mountaineers do in extremely frigid conditions, where a comfortable day might be minus 20.

I share your opinion of what most preppers appear to be,, at least judging from postings on the internet. For my part, I will try and contribute to the resolution of the problem, a strategy I have followed for the last sixty years, both as part of my job, and as a volunteer.

Turning away from problems and hoarding your supplies isn't contributing to resolution of a problem. Sensible cooperation will win the day - witness the Thai Cave situation just one prominent example.

incidentally, where I am, and where i have been, effective resolution of problems occurs much quicker than a week, typically within hours.
