This has become futile. Your distinctions from my perspective are arbitrary and pointless. When you appeal to arguments of absurdity, you lose the right to distinguish that one scenario is more likely than the other. Population is a direct cause of consumption there is no way of divorcing one from the other. They represent both inputs of production and inputs of consumption. The examples you are using suggest you don't understand economics.
I don't need an argument in favor to suggest that marriage should be allowed for all groups. The law is supposed to be impartial. The burden of proof is on you.
