This discussion reminds me a bit of a classic article from the blog that got me into ERE:

Personally, I have invested in some things that will give me a buffer in case of a food/energy shortage, such as dried/canned food, a wood stove and firewood, and so on. But the marginal value of these items drops quickly, in my opinion.
For instance, let's say you have one year's worth of food storage. Sounds nice, but if there were really even a two-month global food shortage, you may have enough food but most of your neighbors certainly won't, so then your concern is going to be them breaking down your door to steal your food to avoid starvation. Buy a gun, then, you say, but those people will also likely have guns. The point is that there is a real limit to the usefulness of disaster prepping. I also don't think trying to live in the global south is going to make you safe from the effects of a major upheaval. As world markets become increasingly correlated, they will be subject to the same shocks we are.
So my strategy is to hedge my bets (as in the abovementioned article) and prepare for the possibility of mild or intermittent food or energy shortages, while also placing some bets on the possibility of none of that ever happening and continued prosperity.
Also, in terms of web of goals, I actually enjoy heating my house with a wood stove. Cutting/hauling/stacking firewood gets me outside and gets me exercise and the radiant heat from a woodstove is the most comfortable type of heat I've ever experienced. Having dried or canned staples on hand saves me a lot of trips to the supermarket (I can usually just buy vegetables from the local farmer). So ideally whatever efforts you are making to build resilience should also improve your life in the present.
