With these points of mine, I hope I've succeeded to convince you why Satoshi Nakamoto is very likely to remain anonymous till the end of time.
Sounds like a debate between you and you trying to convince yourself you said something valid enough.
Anyways in the first few years of bitcoin it was best to remain anonymous just as Satoshi did because if he had revealed himself back then he would have faced a lot of attacks just the way bitcoin was attacked by governments in the first few years but recently it doesn't matter anymore who created bitcoin because it's decentralised and no one has autonomous power or ownership of it rather the masses makes the decision of what happens and what does happen.
Today those who would have prosecuted Satoshi are now buying bitcoin for their economy so it's what it is.
