There are people who argue that BTCers should have some gold for certain scenarios, for example a near term major societal collapse. (I'm not here to debate about that.)
What are other candidate goods that can serve this role? It's not about stuff that would only become valuable in a collapse, but rather stuff that is already valuable now.
Some initial ideas:
-Laundry detergent
-Artworks? Does taste vary too widely?
-Some canned goods are pretty expensive per ounce and pretty broadly desirable
-Some foods like coffee, tea, or flour might work but you'd have to address possible spoilage?
-Bicycle electric assist units?
