Ah, but you forgot that this particular homo economicus has a utility function valuing only reproductive fitness. By suppressing emotions like empathy, guilt, shame, love, and ordinary creature comforts, he is able to make a fortune and pay/bribe sperm banks in countless countries to use exclusively his own sperm; by the time he dies heavily in debt (a poor decision by his creditors), his sperm has been used in tens of thousands of inseminations, almost all of which come to fruition, and he is officially the Most Reproductively Fit Man in the World.
