This is an obviously broad question since it can lead to a rabbit hole of theories and assumptions but let’s try and be objective here.
He has almost a million bitcoins right? Worth a few billion dollars. Some people have claimed some of that money, some have claimed his identity, and I’m sure there’s tax implications and responsibilities for having ownership of those kind of funds. So it leads me to believe that there is a reasonable legal need to acquire his true identity through some sort of subpoena. With all these court proceedings with the likes of Craig Wright and such, why hasn’t anyone looked into the registered name/information of Bitcoin.org? Maybe he used a prepaid credit card paid with cash in an undisclosed location with no cameras and used some crazy proxy and left zero digital trail. Or maybe he didn’t?
