Not all decommodified / cooperatively owned housing needs to be the sort of social housing that tend to come to mind when thinking of a "housing co-op."

Check out the work that the Beverly Vermont Community Land Trust is doing in Los Angeles: https://laecovillage.org/community-land-trust/. The "eco village" operates in this more crunchy, housing co-op sort of way, but then there are also lots of tenants and home-owners alike who live on the land owned by the land trust, without owning their homes in the standard sense.
