Barton,
I can agree that what "Used To Be" isn't there anymore. What could be counted on, based on our National History of how right and wrong was handled, and what one could plan on for future days isn't there anymore. The illusion is there, but not the core values nor the resources of either a Nation or even a Neighborhood....
Now, the only things that can be counted on if/when the economy hits bottom are the food/water/life insuring items like ammo, guns, tools, heat, limited/reduced power, and a safe place to stay and sleep at night. Trading chickens for a doctor's visit is on the way down and at the bottom of the the bad times. So, having whatever size PM bullion you have put back to insure the basics, and maybe a chance of some prosperity, can/will be confiscated from you by the reigning leaders to fund their lifestyle and military and law enforcement muscle.
Let's carry this gold/silver thing another step. If the national powers deem that holding gold or silver bullion is illegal as both were, how are you going to use the bullion coins or bars in the worst of times if it's against the law to own PMs? The biggest issue of "another piece of the puzzle" will be refining the metals to 99.9 levels. Maybe, here is where Sterling silver and the Karat-ed Gold levels in jewelry can keep it away from the bad government guys. I supposed it's going to depend on how badly they need/want it. Even "Rolled Gold" and Gold-Filled jewelry would become well worth refining into legal purity used for wealth or commerce.
So, a part of a person's PM slice of their net worth portfolio should be in jewelry. It may offer protection as well as options for the worst of times when bartering or "wealth status" become powerful hedges against the loss of the basic needs and needed services you'll need because you don't possess the skills or tooling to do them.
