Actually, I believe that human nature is such that no one will hide without much sense.  If Satoshi Nakamoto would face criminal liability with a long term of imprisonment or his life would be in danger, then his secrecy and anonymity would be true.  But if there is no danger to this person, then most likely this person has long passed away or Satoshi Nakamoto never existed at all, and under this name a group of bitcoin developers may have been hiding.  And as always, my words are just one of hundreds of thousands of assumptions.
