The title is clickbait, I presume. I can't read the full article either, but in the introduction it already says that the problem is that not enough houses have been built. And in my opinion, that plus regulation failure are at the root of the problem. Who actually owns the houses is of lesser importance.
But if the owner is the city or state, they can plan and build accordingly. So in the city I live in after the fall of communism almost all of the state-owned flats were sold to tenants very cheaply which was great, but now it's very hard to build anything new. Even old flats are horribly expensive, which is great for sellers like me, but not great for people that want to come here to work and live.
On the other hand, we have cities like Vienna where a siginificant part of the housing stock is owned by the city. They are able to build new neighbourhoods. As a result, while my city is much smaller and less economically interesting, the price of housing is now near Vienna's levels, if not even higher. That's not good for the economy of our city either.
