He's probably way less smart than he believes himself to be. But he's already tried in the past to get out of problems by throwing a a curveball to the issue.
Boring Company / Hyperloop existed mainly to stop California from building their own high speed rail, and The Tesla Truck existed mainly to rebuild hype around the Tesla brand at the time, and it's probably never going to go into production. Both were "built to fail".
Once he realized that he couldn't get out of buying Twitter, I believe he's trying to apply the same script to make sure the loss is way smaller than 44 billion dollars.
