MtGox sees flows in and out every day of a great deal of money through multiple payment systems and conduits; one faucet being turned off doesn't prevent every other flow from instantly and massively reacting to an existential threat to MtGox especially because so many of those users will be non-Americans who are not directly affected by American accounts being frozen; we did not see this massive reaction and panic. Hence the price is a perfectly reasonable indicator of overall confidence in Mtgox.
