You're insane.
I would not give pocket change to anything even remotely related to Mark. He is obviously pathologically incompetent and dishonest.
Secondly - Bitcoin is supposed to be decentralised. If we cannot allow parts of the Bitcoin ecosystem to die off, we cannot make that claim. We should let MtGox die and use this as proof that the network, the community, the technology is decentralised and resilient.
Opting for the "too important to fail" position dramatically weakens the evolutionary process of Bitcoin services. It should fail, and fail fast. This is the market in operation.
