Upthread I quoted (actually @figmentofmyass quoted and I responded) where Satoshi stated that v0.1 locked the major protocol decisions in stone. His point was that once he left (given that he was the creator of Bitcoin), the protocol would be immutable. When Satoshi made the decision to explicitly announce setting a hard limit of 1 MB in the client (before that any blocksize was only apparently a suggested limit, which implicitly provided a Schelling point) and then chose to disappear without addressing the pleas to raise the blocksize again, he had left us with a legacy, immutable Bitcoin with a 1 MB hard blocksize limit.
