Not the ETF's Cork, It's the ETF's.. If they were required to have the Physical to back shares then it will work. Problem is they only Own 1 Ounce of Gold or Silver and sell that same Single Ounce to Everybody. (Did you ever see the 3 Stooges make Chicken Soup? They just Pour Hot water over the same Chicken:)
Musical Chairs, When the Music Stops and they find that Banker is already sitting in the Chair with his One of Gold and Silver there will be over a Trillion Pissed off Investors. At that time Gold will be $50,000 an Ounce and Silver will be $5,000 an Ounce.
