If you just dump a bunch of metal in a bucket and melt it down willy-nilly, you'll only end up with shitty pig iron that's barely fit to hold two pieces of wood together. That's what you'll have by allowing individuals to determine their own mates--as is done now in most of the civilized world--since the average person isn't going to be forward thinking enough to ask their lover for a full family history before they fire a bunch of kids into each other.
