Well the inability to get squeezed covering causes people to gamble on it excessively. We're talking instead of people naked shorting a few percent of the shares, they're naked shorting a few hundred percent. This creates immense counterparty risk for the people who purchase the shares and they don't even know it. The same counterparty risk is inherent to all naked shorts. What's unique about the ETF is the magnitude. I don't think the article explained that very well. It's possible that the magnitude involved could be destabilizing to the economy.
