Yes, everything you say is correct (AFAIK), but it's not what I was talking about. The thesis of my comment was this: the collapse of MtGox involved a larger proportion of the bitcoin market than the proportion of the dollar market involved in the collapse of Lehman. Ergo, the collapse of MtGox is more significant to Bitcoin than the collapse of Lehman was to the dollar.
