A more practical solution is housing coops like the BRF system in Sweden. Individual landlordism is mostly banned (there are some company rentals though) - you buy the place you live in, and there are restrictions on renting it out (no more than 2 years in a row, etc.).
It's helped a lot here.
I don't think that social housing is a good solution. It's a complete disaster here in Sweden, with 12+ year waiting times, and massive inequality between those who have those rent-fixed privileged first hand contracts and those stuck in the unregulated wild west of second hand renting. Often resulting in the working poor effectively subsidising wealthier, older people to keep their very cheap flats in the city centre, etc.
