There is another Satoshi quote, already in this thread a while back, that demonstrates Satoshi made bitcoin resistant to change by design. That, combined with the facts that he snuck this 1M change into a release without telling anyone and that he left without providing any sort of warning about it or, upgrade advice, to me is counterevidence that he at least had a pretty good idea it would stick around, or should have.
edit: here is the satoshi quote. context is talking about the rationale for the script language.
The nature of Bitcoin is such that once version 0.1 was released, the core design was set in stone for the rest of its lifetime.
That combined with the fact that people immediately jumped in and stated it was dangerous and could be hard to change in the future... well, it's hard to argue he was somehow clueless and unaware.
But really that's all just a curiosity, satoshi's motivations. argument by authority and all that. plus today, it is what it is.
I think it does mean that you should stop claiming Satoshi actually created what you/Nash are looking for on purpose. It looks more like it was created as a happy coincidence due to a temporary bug fix.
