"In particular, suppose MtGox"... ahm hold that thought. Now imagine that MtGox are out to destroy Bitcoin becaude they dont give a shit about it and the whole point of MtGox was to steal. Theyve succeeded and they arent giving back any money. No they arent going to lift a finger for the community or bitcoin.

Now step out of your bitcoin is awesome bubble and realize money is not only trust but also power and force to coerce some kind of fairness against these greedy assholes like mtgox who destroy for everyone else.
