Earlier quoted context omitted.
It’s hardly irrelevant. Proved by the fact the people voted for a vacancy tax and not an unused GPU tax.
/me facepalms That’s circular. This discussion of GPUs started when tomcam asked why a tax on unused housing was OK, and whether or not it could be extended to a tax on unused GPUs. In particular, a vacancy tax seems to force people to rent out property rather than merely posses it. Can the same law be used to force people to enter into other rental agreements? I have a bunch of old computer parts, including motherbo…
But to steelman the strawman you're putting up here, economics tries really hard to maximize the efficiency of markets, the idea being if you've got something you can make money with (e.g. a CPU/GPU/book/bike/car/bed you could rent out) you should, and thereby someone gets to use your thing and you get to make a little money. You paint this as some kind of hyper-communistic dystopia, but this is actually the world that hyper-capitalist companies like Uber and Airbnb are working pretty hard to create right now.
This is critical to understanding the anti-democratic underpinnings of this landlord action. There's nothing unconstitutional going on here--it's basic market regulation that States and the US have been doing for literally hundreds of years. There's nothing wrong with policies aimed at making markets more efficient, that's why we have regulations and antitrust.
And besides, rental housing is a market. Hogging supply to artificially inflate market prices is generally a crime. Suppliers in this market are suspected of doing that, so the people of SF are taking action to make them stop. They're lucky they're getting off with a tax.
That said, I'm not a fan of this policy in this case. SF's vacancy rate is super low, and I think that indicates this tax won't result in meaningful revenue or vacancy rate increases. This seems like purely a supply problem. I know there are other places (Vancouver, Toronto, NYC) where "property as investment" has gotten out of hand and municipalities are passing laws to try and address it, but they had way higher vacancy rates than SF.
I could be wrong though. Others have made the argument that SF's market is secretly inefficient, that for one reason or another landlords are reporting their units as occupied when they in fact aren't. In that case, this tax might motivate those landlords to rent their places. I don't buy this though, in particular I don't think many people would leave > $30k a year on the table just to have the option of one day letting their parents move into a unit.
