Adam Back is the well-off CEO of a company in the blockchain space. From that position, he gets to continue to use his expertise in the field with plenty of connections while having more than enough money without needing to risk revealing himself as Satoshi or risk de-stabilizing Bitcoin's value by using Satoshi's known wallets. It seems like the best possible outcome for someone in Satoshi's position.

I'll at least agree that I don't think any other living candidates for Satoshi make any sense. I can't believe someone who started a brand new influential field of study could fully exit from it while fully avoiding the proceeds from it, as would be necessary to believe in any other living candidate.
