Well, the bar example is fairly interesting: in lots of localities, that's exactly how things work. This is one thing that leads to bar or nightlife districts in cities, as no other residential areas want to deal with the issues caused by bars.
It is hotels complaining, for now, and I don't think anyone is taking the POV that we should respect their legally privileged position just because they already have it. But a lot of these and similar laws have existed for awhile, because various bad actors have abused short term renting in the past. And if Airbnb and similar setups become more widespread (as they're bound to do), we do want to have some legal framework to deal with issues as they arise.
