I tend to think this, too. Or rather a small group of cryptographers working for a nation-state. It's the only way to make sense of the fact that Satoshi is enormously wealthy. I don't think any individual could sit on this kind of wealth and not cash out visibly.

I've subscribed to the nation-state theory as well, but intentions unknown.

It was the CIA and anyone who aren't starry eyed tech dorks has known this forever
