This thread makes me want to buy a cheap chest freezer just for backup. I'd be so screwed if my freezer gave up the ghost.
The high demand for freezers started way back at the same time as toilet paper. The virus panic caused people to plan for an eventual food shortage. I already had an 8 cu ft chest freezer, plus the freezer sections of two refrigerators all about 2/3 full of food, so I too wanted some kind of backup. I got a cheap $350. chest 9 cu ft freezer from Lowes in late February and mine was one of the last two that were in stock. Home Depot was sold out. Vacuum packed food has a very, very long "shelf life" when held well below 0F, so I added a little more food.
Investing in a couple of small Honda or Yamaha style inverter generators is also prudent. They won't run large loads, but my Honda 2200 supports two refrigerators and a chest freezer overnight on the 1-gallon internal tank.
Same with ammo and other basic supplies - you buy it while it is plentiful and sale priced. No hoarding required, just a little forethought. As a kid, I grew up in different areas, but mostly in remote areas where you learn to be more self-sufficient and reasonably prepared for minor emergencies lasting a week or three. Stuff breaks, so I follow the reasoning "one is none, two is one" for stuff that is important for me.
