I follow your line of thinking and mostly agree... however, would like to also point out that barring apocalyptic scenarios - there are always deep safe value sinks if you consider your needs from first principles.
Consider for example having the capacities to produce your own energy (food and electricity/heat) - these are core expenditures for most people besides a place to live. All these are direct consequences of productive land control (you can even live on the land you grow food and have solar panels on).
So if one owns and develops an environment to supply their fundamental needs autonomously and near-automatically - that would seem to be a deep value store that is about as long term as the environment can hold up.
Edit P.S. we've observed what industry has accomplished with vertical integration... why not apply it to our inputs, to increase autonomy of abundance in outputs?
Yes on a personal level you are right, and that is a good idea.
