In many lights the reason for this loss is irrelevant. Stories like this affect confidence and thus the core of Bitcoin. There is clearly a need for a body / brand / bank to give a sense of certainty to Bitcoin holders in the event that bad things happen.

It's a simple insurance opportunity and it could be that a very small premium is required due to the inherent safety of Bitcoin but your average man in the street doesn't understand / care, all they want is certainty. That's what has worked so well for Visa & MC for so long. It seems a prime opportunity for a very successful business.
