Isn't the "ruining" of cities more due to general lack of affordable space in light of increased urbanization and tourism? Granted, Airbnb will add its share to the overall shortage, but if I'd take all Airbnb apartments off of any market, would this put rents back to an affordable level or curtail tourism? Airbnb reminds me a bit of eBay - good idea led to an influx of professional sellers, which at some point had to be regulated (register as business, taxable income) and in growing up, the platform lost most of its appeal and discoverability of the things it once was created for. Still fills a large enough demand to be around. I'll call the same for Airbnb: There's demand for staying at a place which does not feel like a hotel and I found the Berlin ruling made for Airbnb to be going in a good direction (Zwecksentfremdungsverbot - use Airbnb if you rent out part of your place, but if you rent on as a business, it must be registered as such). I'll expect other cities to follow suit, because it also postpones having to address the underlying issue. (regular Couchsurfing host and sparse surfer)
