Adding more houses to the market certainly will decrease pricing pressure. Nobody said banning Airbnb was suddenly going to make housing affordable but decrease prices.

And my question remains, which is more valuable to society, short term rentals or homes?

It's not a zero-sum game. You can have both, but you need to build enough to have it. Regulating the use of a thing is a mark of market failure. How would you feel if the government told you that you could only use a pencil for writing because that has more social value than its use in making a model log cabin?

You're also failing to process my point: that banning short-term rentals is an ineffective lever, not that it won't have an epsilon of impact. Yes, you will increase supply by a tiny amount relative to the shortage. It will have near-zero pricing impact because the magnitude pales against the problem.

No, we have been ignoring your point because it’s one of those Econ 101 world views based on assumptions that have no basis in the real world and actual human behavior. You can’t look at the number of Airbnb rentals and conclude it’s not having a significant impact on the market simply based on the raw number of units. What we know from all systems theory is that a small portion of things has the majority of the effect. In this case, short term rentals are very likely setting the upper bounds of the pricing range.

Actual research suggests the effect is tiny.

"At the median owner-occupancy rate zip code, we find that a 1% increase in Airbnb listings leads to a 0.018% increase in rents and a 0.026% increase in house prices."

Clicks on "actual research," finds the usual econometric voodoo. Even better, the use of instrumental variables to supposedly "isolate" effects. Totally representative, I am sure.

PS: the author's own words contradict your claim that the effect is tiny, although again I think this is a serious undercount resulting from a poor model and ever worse availability of data nationwide: "This means that, in aggregate, the growth in home-sharing through Airbnb contributes to about one-fifth of the average annual increase in U.S. rents and about one-seventh of the average annual increase in U.S. housing prices." https://hbr.org/2019/04/research-when-airbnb-listings-in-a-c...
