No physical shortages of goods or materials here. Mostly I'm worried about being run over on the road by an Amazon van delivering stuff.

There is a shortage of "affordability" though. From groceries to housing, urban folks are under some pretty severe stress.

I am fortunate to have a buffer to all this, even though I drive a 10-year old used car. For a several decades, I have done the same as my pioneer grandparents -- my long-term "preps" involve growing a ton of food, building soil fertility without supply chains, and sharing surplus with my multi-skilled neighbours. I also have more wood than I can burn, and the skills to use it. It doesn't solve everything, but I certainly sleep better.
