A Pomeranian is also not a communal good. Dogs are still recognized as property - while I may not agree with that because they are living beings, societies do not center themselves around dog ownership. I don't care how many doggie daycares open, they're not the same thing.

There are few societal absolutes - the obligation of a society to recognize the need to reproduce and balance the rights of parents with the needs of future generations comes closest to an absolute. Simply because you believe the poor should be stripped of their children and right to reproduce does not make it a societal value. And thank God.
