One of the old theories out there was that satoshi was a group of people and not just one person. I think it's much more compelling argument that Wright may just be one member of that group. But, why claim that you are satoshi after all this time is lost on me.
why do you and many others here say that he's claiming to be satoshi? quite the opposite... he was 'outed' by hackers and journalists and now appears to be on the run. and has shut down all of his digital personal footprints (closed twitter accounts, youtube etc)... nowhere does it say that he wanted to be known as satoshi, except in private emails (that were made public, presumably without his knowledge or involvement). if they were deliberately leaked by him thats another matter entirely!
this doesn't - on the face of it - appear to be a man trying to claim publicly that he's satoshi (at least not directly). he is giving the impression, perhaps, accurately, that he's in hiding and doesn't want to talk to anyone. he's cut off all communication with everyone. if he's a fraudster, he's certainly a very reluctant one. as mentioned in m previous message, he seems to be extremely techie, and has most of the skills required to have done the job.
