Would Ishmael have thought that the ancient Greek governmental system was fair?

No one really knows what Ishmael would think. I know that the ancient Greek government has basically 4 kinds of government: monarchies, oligarchies, tyrannies, and democracies. But I think we are talking about the time period which Plato was in, in which the women and children were to be shared. I think that Ishmael would think that this kind of society is wrong, because Ishmael basically stands on nature's side, and in nature, when an animal is born, usually, the animal belongs to the family, and no one else, of course there are a few exceptions. Basically, even in nature, the animals have the right to own their own children, then shouldn't humans should as well?
