I believe MtGox users have unfortunately learned the definition of "counterparty risk". This is one of the major overlooked risks that almost took down the global financial system in 2008. People would hedge their worthless bonds using AIG as a counterparty, and once things blew up, these people realized their insurance policies were completely worthless because AIG was about to go under itself, causing them to almost go bankrupt as a result.
Unfortunately, in a world where none of the bitcoin exchanges have any sort of regulation, there's no way that BTC use can expand via BTC financial institutions until people have full confidence they can get their money back in the case of another collapse like mtgox.
