My Theory:
He is a quiet guy who reads stuff like bitcoin twitter all the time.  He and another guy who is local with him may have created the experiment.
This guy had access to the real Satoshi and likely interacted with him at school.  This Satoshi Nakamoto is the guy everyone is looking for.  The real one, who is hiding behind this online persona of the actual programmer friend, is the guy who wrote the early series of emails and is responsible for inventing Bitcoin.

Why doesn't he come forward?
He simply doesn't want to be associated with the name.

Doing some analyses of the early emails, the language appears to be incongruent.  Which supports the idea that he is one guy hiding behind his programmer friend's name.

I would say that if he were to be found somehow by some random person that he would run away from them or maybe confront them.  Extremely unlikely he will be found.  Likely nil.  Probably are traces of him on the Internet if you look hard enough under his real name, but most likely its been deleted.

Everyone should build the Bitcoin whitepaper as a niche reward etched onto the blockchain. Randomized for select users or randomise it to every wallet.
Users get to interact with it in the software even more and can inscribe their cryptographic language, or their own dialogue animations into different niches of it. Either way, miners will still be reading the whitepaper without knowing it and they should.

I'm pretty sure that there is a business law blocking this act in most countries, but I can't think what it's called. There is also another law, but I think it is the one you have pointed out. I'm not a lawyer, so can't really say.
