Denmark doesn't have government owned housing rented at fair prices. It has housing orgs which are beholden to special laws but are still private businesses. Because these businesses own a whole block of apartments, they can strike good deals with the municipalities to house or accommodate the less fortunate. If you are middle-class then you do not live in a housing org that houses the lower class. We don't share space.

I live in the cheapest apartment in my city in the best housing org arguably in the whole country and I still can't pay rent and my landlord won't come and fix the several missing doors. My neighbors are fruit-fly breeding enthusiast druggies who don't have to get up in the morning for anything but groceries and love to party all night on any given weekday despite the housing org rules but the housing org won't do shit about it so I regularly don't get to sleep and the cops don't respond to noise complaints from renters unless you live in a good neighborhood. I also don't have hot water in my heating system but to be fair I haven't told my landlord that because I can't afford heating anyway.

Denmark does not have a housing model that should be an inspiration to the rest of the world, especially not since the jobcenter is also partly responsible for housing you if you're out of the job market and entirely responsible for you and your rent if you are handicapped, both of which are conflicts of interest and they have been documented to hold this power over vulnerable people so they can continue to have their labor exploited through "activation" programs. I'm perfectly capable of working despite my handicaps. Alas, the jobcenter has struck deals with local businesses and they won't give me any of those jobs I can do because the jobcenter can just force me to do it and then not pay me so I can't ever hope to move to better pastures.

You might have been thinking of the Netherlands, but their government housing isn't exactly a perfect system either but it's better.

Decomodify housing.
