It would be better if Satoshi simply burned a majority of the coins as an act of solidarity with the community. Someone owning close to 1 million bitcoins is a deterrent to outsiders from participating and a security risk to the ecosystem.
If you are really convinced that him owning 1million coins is a too big risk for the ecosystem, you should look into an alt-coin.
I only try to say that the market doesn't really care about him owning so many coins.
And besides, he could better donate them to everyone than burning his keys because if he donated them to everyone you shouldn't be afraid from him spending them ever.
But I don't really care about his coins. Bitcoin is much more than price for me.
Hell even when bitcoin died completely it gave me the biggest lesson I would have ever learned.
