For whatever reason it still leads us to unintended consequences.
Would the courts allow a law that said only a man and a woman could form a Corporation? (doing so to engage in tax benefits and legal protection of personal assets)
Answer would be no based on the equal protection clause and the courts will use the same for marriage.
I'm not saying this is how it should be I am saying that legally this is what happens when the government starts granting goodies based on the sex of those involved. The Government should have never granted financial benefits based on married status.
red herring.
corporations do not produce future citizens.
corporations do not give birth.
This is not about ownership or property.
This is about society continuing society and society rewards the institution not the individual
corporations are about individual reward.
even a childless couple proves the model.
