The matter of judgement comes down to "Who's judgement?"
AirBnB clearly thinks it is fine. The people on either side of AirBnB renting may think it is fine. People living next door don't get a say, and yet have to deal with the social outcome. They want a say.
Why do they want a say?

I think "it is up for debate" as to how to proceed in future. I don't think it is up for debate that we can continue without change.
