I understand your confusion (or sarcasm).
The list is confusing because the author of the piece is not thinking correctly, which is two scenarios.
The first is a complete breakdown of society that sends us back to the dark ages for a few years at least. In that situation, you need only survival goods and skills and partners.
The second (which the author assumes) is the dollar dies and we go into a severe recession (newsflash, we’re already in one) or major depression. As the dollar dies, people lose all their savings and most importantly the purchasing power of those savings. The fine art item on the list is for this situation when the author assumes we will rise back out of the recession/depression but with a new currency in place. When that currency takes off and becomes established, the people who have that currency will buy the fine art and replenish the purchasing power that had been lost when the previous currency died.
Thanks. I agree with your response in post 96.
