Online account recovery could go a long way by bootstrapping off the notary system, and then having a waiting period to mitigate forgeries. But companies don't want to add the complexity where a user could commit to a less convenient process for more security, so we're at an impasse. Also they'd have to hire someone to verify the authenticity of incoming physical documents, and having skilled labor do things that aren't "scalable" is verboten.
