If you were a community, municipality or country committing to the principle that all people deserve shelter, how would you make that principle a reality?
Public housing. What I am would really make the difference as to what I could do.
If I was a community I would try to acquire property and build the highest density property that made sense and make sure it has a park or land close to it.
Could build a farm next to it to provide jobs and healthy food to the community as well as potential vocational training.
Would focus on getting sane public transit to and from the area. Hopefully after a time private sector would start building up the area and we could locate another area to bring the model to.
Farms only need like 2-20 people to work em, not a great source of jobs
You could provide regular buses to nearby towns fairly cheap, depending on the geography. Then people could live in your community and commute to other ones where the jobs are.
Some do, some don't. Non mechanized crops require tons of manual labor that is paid at sub minimum wage during harvest.
We could think of ways to use more people by expanding it to more than simply growing food. Perhaps a coop that sells the food too? But yeah not perfect.
If you take it out to its logical extreme, you're just reinventing existing society. Which is how all anarchist/libertarian/etc thought experiments always end
