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
One more possibility: Gavin knows who real Satoshi is and doesn't want to reveal his identity. Gavin saw Wright as a way to distract public to wrong path (but unfortunately it backfired, as the public "proof" was so clumsy).
IF gavin knows who satoshi is. then that would go to the first possibility because gavin could've kept quiet. instead he risks losing everyone's respect by backing a silly claim from a fake (again, IF).
