There are simply too many big players (hedge funds, investment banks, etc) with heavy exposure to Gold who would be forced to liquidate their positions during a systemic collapse.
The only thing I'll add, why would hedge funds, investment banks, Wall Street have heavy exposure to gold?
Watch CNBC...they all hate gold and always say gold is a losing proposition.
That only leaves central banks that are holding gold. So is the author saying central banks will sell gold into the next crash?
