In the new economy, bullets and beans will beat gold.
Also, if you have to move your wealth, it’s hard to tote around $10,000 (or $100,000) in ammo or food without a big truck. That amount ($100,000) of gold weighs less than a gallon of milk, and can fit in the pockets of your cargo pants.
Google FDR and gold and you can get the wording of the executive order. Gold hoarders were "bad" people, not people trying to save their savings.
Fascism makes bad people from regular folks and makes internationalism the goal. That way you are hurting the whole world population if you have gold. The same if you breathe out carbon dioxide or drive an SUV, ect.
I've had the discussion before about the 2nd Amendment. IMHO, the "right" of gold possession will be easier to get rid of than guns, because it isn't specifically mentioned in the Constitution. I also think it would be difficult to "make change" for an ounce of gold if it's worth $10,000. Even if a loaf of bread was $1000.
