Satoshi Nakamoto created bitcoin to be anonymity therefore he has to be anonymity as well because if he shows himself then the US government will arrest him and ask him to destroy bitcoin. And they will be different accusations on him and the one they will use to against him is the money laundering. Which is the back bone of the US government to accuse any privacy company in the cryptocurrency ecosystem to ban them and we have seen it from the mixers perspective.
Moving but bitcoin is not the problem of the matter, he can move bitcoin past anytime of his choice. How many bitcoins are the Satoshi Nakamoto Genesis bitcoin address? Did you know the amount? I don't think they are not much. And I also think the main address he is using is different from that first address. I believed even now too he is going to El Salvador bitcoin conferences.
Yes anonymity is the number one identity in the ecosystem. And to my children I will but depends on the age they are.
