I agree.

Many have disagreed with Gavin over many decisions, but I've never seen any indication that he's "dumb", "unintelligent", or "lacks intellectual curiosity".  I'd certainly expect him to be careful about verifying a signature as well as being careful about what was being signed.  I doubt a scammer would be able to convince Gavin that an invalid signature was valid.

This leaves me with five possibilities:

• Gavin has lost his ability to think properly
• Gavin is part of a conspiracy
• Craig Wright is a better scammer than I can comprehend
• Craig Wright got a hold of some of Satoshi's private keys somehow
• Craig Wright is Satoshi
