Only an idiot hoards gold to USE during a collapse. I bet any Japanese that still had their gold stash was much happier by 1948 or so. Gold let’s you rebuild after the crash.
That’s the thing: most people don’t grasp that gold carries value to the other side of the crisis - it’s not much useful during the crisis. I expect few indeed will know how to use gold mid-crisis, and it takes two to transact.
