In my opinion, anybody who thinks 'Satoshi' didn't create Bitcoin with the intention (at least, in part) of getting rich, I think you're fooling yourself.  It's clearly built into the structure.

At this point, it's in the hands of the community.  The OP's post is relevant because depending on how many BTC Satoshi owns, he can cash out at any time.  The stronger the community becomes, that gives Satoshi less incentive to cash out immediately.  If there are overwhelming signs of an absolute market crash, Satoshi is the one who can solidify it.
