He owns like $100 billion in bitcoin, so I think unmasking him as either someone who just has chosen not to use that money yet, or someone who died with the keys likely lost would presumably have a big price shock. Once he is identified, he and everyone connected to him becomes a massive target for organized crime and such, that many coins ending up in the hands of North Korea or something would probably significantly damage bitcoin's future; I imagine the feds would do whatever they could to ensure that can't be turned into spendable money.
