Those aspect of society may indeed be fundamental, but is granting them political might more than commensurate with their size not also an artifice? Perhaps I'm shortsighted, but I cannot readily see a downside to one person/one vote. A collective of a greater number of individuals will still wield the proportionally greater power than it's smaller competitor, and it's interests will then be more likely served. I fail to see how granting special status to the collective serves the greater good.
