"I asked how this section restricts me from requiring that a guest email or text me a copy of their ID off of the Airbnb system. I was not given an answer only that it is prohibited. Period."
Exactly- you weren't given an answer because I believe the CS rep you were dealing with is clueless and intrepreted that policy wrongly.
I have a friend who hosts tell me that she has had to walk CS reps through their own policies to prove that what they are telling her is not at all true. She has her calendar settings to only allow bookings 3 months out. She got a booking for a date that was 2 months past when her calendar was open and called Airbnb to get them to cancel it. The rep told her it would have to be a host cancellation and she'd be penalized. She had to insist, and not give up, and in the end, the rep realized that it was an Airbnb glitch and there was no way my friend should be penalized for it.
You were treated very unfairly. I've found that if it is obvious that a CS rep is not going to be helpful or sympathetic or is simply a clueless robot, thank them for their time, close the conversation and send it again as a new issue- you'll doubtless get a different CS rep and don't mention that you've already discussed this with a different rep. You might have to do this several times before you get a knowledgeable, helpful, personable rep.
