Fuck the cybertruck but I agree. To me, it looks like a firm layer of ice and a distinct lack of tires which can handle ice or chains failing that. Cybertruck’s weight is doing it no favors here either, and the load helped pull him down the hill. Chains would have made a huge difference in this condition.
I’m going to say a few things about food and also assuming prices will go up and not quite reach an economic collapse:
Secure your food, learn to prepare cheaper, more plentiful foods in a way that is tasty to you (look to rice and beans). Consider purchasing or creating emergency food reserves. Consider purchasing more canned foods which can last for years. If you have freezer space, consider vacuum sealing food to keep them for longer.
Generally, look for ways to reduce extraneous cost and rely more on yourself and your immediate community. (This will be difficult to do, no mistaking it)
I mean, if you look back to the framing of the constitution, the idea was that a bunch of citizen militias would be kept such that if the country needed defense, they would be able to respond. This was because the new United States lacked (and politically opposed) standing armies like the one which they just fought off the continent.
Since then, the United States acquired an Army, Navy, and Air Force alongside numerous National Guard units. The theoretical need for citizen militias vanished.
The real answer to your question is that we really don’t have citizens participating in “well-regulated militias.” Not from the constitutional context, anyway.
