It sounds like whoever managed to get political support in that community is making the economic decisions, rather than “themselves”. Individual property rights simply devolves that control to the individual or the family. Communal property rights would place control of property into the hands of the elites.

It’s at least possible today, and leads to the collective increase in standards of living.
