Unfortunately as good as the intent is, a malicious user with devious intentions can simply forge an ID or use one of the many IDs they've already stolen from their unsuspecting AirBNB hosts.
I believe the best solution for fraud is to require the user to take a webcam shot of yourself while holding the ID next to your head. I had to do that once to verify my identity.
The effort required to photoshop such an image (or paste your own picture on top of a stolen ID) is trivial compared to the effort required to forge or steal the ID in the first place. Thus, I don't understand how this would be anything other than an inconvenience to honest users.
Requiring IDs like this might actually facilitate ID theft because criminals could create fake host listings and then request all sorts of information like this in order to steal identities. Much easier than breaking into houses to steal them.
Oh I know it is in that service but I don't think that's what the poster I was replying to was suggesting. He's suggesting as a host that you do that (although perhaps I misunderstood).
