It could be a reason that Satoshi was a criminal, thus he wanted to protect his identity in order not to give to the invention the name of "the creation of a criminal" and make people think that it is something bad.
This would be a great case that Solotshi was the creator that never passed my mind.
Do you post everything under your real name ? , privacy is a thing for everyone and he was planning to implement a platform that could potentially challenge every forms of financial systems and government printed money and you think he should do that revealing his identity so that the authorities could knock his front door the day he released the bitcoin software to the world

.
The real Satoshi is dead and if he really wanted to rise up again, he will do so in his own terms.
