Finally watched the HBO doc. I always concluded the same. My evidence was, having been a teacher for 15 years pre-bitcoin, the tone of Hal Finney to Satoshi comms were very much mentor to young person, ol'Todd always fit the profile. Young upstart smushing technologies together and annoying a bunch of grey beards.
I also loved the idea of Satoshi hiding in plain sight and travelling the globe trolling fuck out of bitcoiners.
Certainly my fav possible Satoshi (not that any of it matters).
