Another reason why landlords need extreme oversight.
you mean _because of_ supply and demand, rather than in spite of?
So to fix the problem isn't to regulate landlords (aka, attempting to legislate price controls), but to produce more supply.
It's both. Producing more supply works best when it isn't being sabotaged by landlords intentionally keeping units vacant.
they should be free to do so. They have a holding cost, which they're going to have to pay.
I mean, why don't wheat farmers intentionally hold sales of wheat to force the price higher?
GP means _in spite of_. It's the only way to explain the number of apartments kept vacant to artificially reduce supply.
See below for instance.

The latest New York City Housing and Vacancy survey estimates that last year 26,310 rent-stabilized apartments were “vacant but unavailable for rent,” down from about 43,000 in the same survey two years ago.[1]: https://www.nytimes.com/2023/04/20/nyregion/rent-stabilized-...
These are exactly the apartments where landlords have exactly zero ability to set price, let along to collude to fix prices.
