That logic works when you're talking about renting out a housing unit (or part of one) that someone already lives in. There doesn't seem to be a whole lot of opposition to that idea.
But that logic doesn't apply for units that are exclusively used as STRs because then you have the same partial occupancy problem as a hotel, but in a much less dense package. An empty 400-room hotel takes up a city block but 400 empty houses take up many blocks. This seems to be the case that most people object to.
So what? Who is to say how occupied MY private property is supposed to be? If I want to leave it vacant, so be it. It's MY private property, what business is that of anyone else? If I want to only occupy it one day out of the year, what business is it of anyone else? If I want a 100 houses, who the fuck is anyone to say I can't leave all of them but one vacant if that what I want to do? It's but a tiny step for those who think like the quoted text to try and impose mandatory occupation rules on housing and confiscate those units not being occupied.
The solution for the "problems" in short term rentals is, as always, private property and individual rights, not oppressive Government rules that ALWAYS favor intrenched special interests (e.g. hotel owners who stand to lose a shit ton of money when travelers have a choice in accommodations - see, the hotel lobby bribes gives campaign donations to the local city council asshats, D's, R's and the rest, to keep out the competition). The worst abuses of the little guy and gal happen at the point of the Government wielded gun - ask any victim of for profit eminent domain, for one example, of how the Government is there to hold down the little guy, not help them, or how about nakedly anti-competitive occupational licensing rules to keep the gravy train going for incumbent business' (by keeping out upstart competition) at the expense of the consumer.
Raucous party from the STR next door? Call the cops and file a noise and/or public intoxication complaint (their noise in excess of regulation is entering your private property, their drunken people are stumbling around in public, etc).
Shit being thrown over the fence? Sue the owner for illegally dumping their property (e.g. trash) onto your property without permission.
STR asshats parking in your driveway? Be sure you have the towing / booting sign posted per local law and tow or boot their vehicle for using your property without permission.
Honestly, I'm not sure there are many people here upset about unoccupied houses. And there are plenty of those too, lots of people own second homes here.
The concern I see is asshats who are just visiting and raise a ruckus.
Now, it's hard to pick your neighbors. We've had a lot of turnover in the last 10 years, and you can always get a jerk for a neighbor. Luck of the draw there.
However, it's different if you have a never-ending supply of jerks. Then there is no learning. You know, somebody parks their big truck in front of my house for days, I can get them towed (if it doesn't move in 3 days). If they park there every night and I cannot see to safely pull out, then I will put a note on the truck to "please park somewhere else" (one of our cars was totaled for that very reason, and I've found the 2 people who parked in front of my house were very good about moving after that). But a new person every two weeks? Making noise, being a jerk?
Or not I guess.
I see the concern from both sides. Residential areas are residential, and are not commercial - they are zoned as such. There are limits to the # of units you can have, the square footage, the number of parking spaces, the # of people who are living there, whether or not you can operate a business. These rules are set in place before you even buy the house, so you can't suddenly say "well, I didn't KNOW that I wasn't allowed to convert my garage to another apartment!!"
Likewise there are areas that are zoned commercial and are zoned as a combo.
It's kind of a difficult spot in some areas -
On one hand, it's my house. If I decide to move somewhere else and rent it out as an investment property - I could make a LOT more renting it out as a STR.
As a LTR, I could get $3k/ month. That would cover mortgage, taxes, ins.
As a STR, I could get $200 a night, or $6000 a month (some times of year more than that). Even if it wasn't fully occupied, I'd only need 50% bookings to break even. And the advantage is that I could actually come home and stay in it! (As I mentioned, I have a friend doing this.)
On the other hand, I'd hate to tick off my neighbors with rowdy people staying there. Houses are close together.
And of course, there's a serious rental shortage. Every single house that gets converted is giving a big FU to all of the people who are already struggling to make it here.
It's not a black and white issue by any means. It comes back to the age old question, "does anyone have a RIGHT to live in a particular place"? I dunno.
