I suspect it has to do with insurance.
I suspect it's to demonize gold, as they've demonized guns.
The Australian Broadcasting Company (ABC, there) a state-owned network, has a 60-Minutes knockoff program. They conned Peter Schiff, who was at the time running Euro-Pacific Bank, a non-lending bullion bank that didn't do USA business...conned him into an interview, and twisted it and made, outside the interview in cuts, allegations of the bank being insolvent and a money-laundering outfit.
Apparently it was not so, but regulators then closed it down. EVEN THOUGH a competitor had offered to buy the bank at a fair price...he was prepared to sell, and the bank examiners were prepared to allow it, but word came down from on-high, and the sale was blocked.
I guess people with deposits are still in limbo after a year of having their accounts sequestered...strange, since the money IS PRESENT...they're still looking for charges to place on Schiff, but can't find any that will stick.
All because he trafficked in bullion and allocated gold storage.
Gold, like cash, like firearms, represents individual freedom and protection. All things the Globalists cannot stomach, in the Little People.
