I'm really not too sure why you're being downvoted. I think there are a number of people who agree that outing him isn't necessary or valuable. A man trying not to be in the public eye deserves as much.
Not just that - outing satoshi could cause him and any close family significant danger, given that there is a strong chance he is in possession of the secret keys of addresses containing 1M bitcoins. https://bitslog.wordpress.com/2013/04/17/the-well-deserved-f...
It's actually really really unsafe for him. The moment people find out that he's a billionaire (Satoshi's BTC are worth a 9-digit figure), he might be a victim of an attack.
Just to be a bit pedantic, he's estimated to have ~1.1M coins, which at current market prices would be worth $440M (9 figure wealth isn't a billion, but 'only' in the hundreds of milloins). Obviously he'd destroy the book on any exchange if he tried to cash out so it's probably worth much less than that.
The owner of those 1.1 million bitcoins can cash them out easily enough - without ever selling a single coin onto the open market. Walk into the offices of Andreessen Horowitz and tell them you want out. Those million bitcoins would be extremely valuable to anyone looking to build a large foundation of businesses around bitcoin.
I wonder how much you could cash out a month without really affecting the price. With that amount you could cash out half a million dollars a month for a very long time, assuming the exchange rate doesn't change much, and live like a king and/or fund the next project
