To the extent that someone could argue that there is some public interest angle, I think that's only arguable in the case of certainty. Speculation is a dime a dozen. Even if there is a public interest angle in identifying Satoshi, I don't think that extends to idle speculation.

Hal was an amazing guy and I feel privileged for the bit of interaction I had with him, refraining from a fun game of public speculation is a small cost. I'm sure if he's cryonically revived in the far future he'll appreciate the consideration. :)

In general speculation like this risks creating a lot of harm for the targets, especially since brutal cryptocurrency related kidnapping and torture appears to be on the rise.

It's unclear what bitcoin Satoshi might have had access too, but people who aren't Satoshi certainly don't have access to it... and the cost of security against criminal gangs hoping for a billion dollar windfall are unreasonable large even for a wealthy person and are unimaginable for someone of more ordinary means.
