> The only reason why laypersons consider email to be non-repudiable is because of additional protocols like SPF and DKIM that were implemented after the original spec
You really think that laypersons have any idea of what DKIM is?
> But the world would be worse off, not better.
That's the whole point of this discussion. You seem to be arguing that the world would be better with non-repudiable email. But then I ask how many disputes have been resolved with DKIM and you have no idea. So basically your argument has zero basis in reality.
You're asking for every email user to have non-repudiation enforced unwillingly to them in every email they send so that someone maybe someday may solve some imaginary dispute with Amazon by using DKIM.
