Can you elaborate on that? The only thing I can think of is the government owns the property and rents it out and can keep the rent to what it costs I suppose. But utilization of the spot seems problematic over the long long term.

High value locations due to proximity to services and public transit would be filled almost instantly and a family could live in that spot for 80+ years.

Someone moving to a new city would basically only be able to find housing in less and less desirable locations. Living in the city center versus 30 minutes out of town would cost the same I assume. You'd really want to know someone who works in the organization that manages properties to know when something is coming available and put in your application before it's public.
