Len checks the most boxes for sure.

But the part that seems strange to me is that cypherpunks and usual Satoshi candidates are experts in cryptography.

From everything I've read from other cryptography experts is that Satoshi didn't have a deep understanding of cryptography. Sure they had enough knowledge to develop Bitcoin, and that is impressive in its own right, but nothing points to Satoshi as having more than just a basic understanding of cryptography.

Also some design choices around privacy and security don't match with the cypherpunk ethos imo.
