Airbnb hosts do do some of this stuff - ie. 24/7 checkin is available if you filter for it, as well as other facilities.
But I do agree that it's becoming harder to justify Airbnb use. As it's popularity has risen, it feels like, what was once a cheap stay in someones house, is now the same price as a nice bed & breakfast. And with Hotel's seeing the lost footfall, the gap between a private room in a strangers home and a hotel room with much more privacy has become smaller and smaller.
I've used it every week for about 8 years now for my accommodation when working away but couldn't see using it much in the future
