Okay, I'll play devil's advocate:

- The Bitcoin logo is the most obvious choice of symbol for *any* currency that starts with a 'B'. In fact, the Thai Baht uses the same symbol.

- The names Satoshi and Nakamoto are extremely common in Japan. This is probably why Satoshi chose them. It's like finding someone from the U.S. named John or Smith.

- Hal Finney can't be Satoshi because Elon Musk is Satoshi.
