So what?
Even if Satoshi holds all these Bitcoins, at current market prices he would only have $15 million.
Compare this to Bill Gates who also created a revolutionary type of software and who now owns something like $50 billion, that's 3000 times more
Yet Satoshi could more permanent damage to Bitcoin than Gates could do to USD. That's the concern for most people.
And the fed can and is doing permanent damage to the dollar, people don't seem to care so much about that. The design of bitcoin is absolute genius, santioshi deserves how ever many coins he has , simply because they would never have existed without him. The chain was public from day one, people just did not know it existed.
