As a digital nomad I live my life in AirBnBs (with the exception of the occasional hotel and housesit). Over the last 2 years I have stayed in ~20-30 AirBnBs in Asia and Europe (we were going to do the Americas this year...alas).
Without AirBnB I don't know how we would be able to live as digital nomads. Hotels are not acceptable because they lack kitchens and laundries (and laptop friendly workspaces).
I understand that we're not the normal tenants, we stay for weeks to months, recycle when possible and rarely if ever make any noise that would irritate other tenants. But I like to think we're not detrimental (I understand this is a little #NotAllMen).
Interestingly, AirBnB is far from a perfect solution for us either (some of the AirBnBs we've stayed at have been absolutely shit). But one of the things the we value as digital nomads is living as the locals live (or as close as possible). Going to the supermarket, living outside the old town.
As far a bad tenants go, before we left Australia we owned an apartment in a fairly average apartment block. There was a council flat within the block, and the tenant was nothing but trouble. Leaving rubbish and furniture around the property. Drinking to excess. Having raging arguments with associates. It does not take AirBnB to have problems with other parties within an apartment block.
(None of this is necessarily negates what you say, just an interesting counter point)
