If it's an accurate way of looking at the world, you've just demolished your own reasons for not having kids.
You don't want kids because it's selfish? That must mean, using objectivist reasoning, that to you not having kids is even more selfish. So your reason for not having kids is no reason at all if you subscribe to that sort of shit.
As for good, in the same way that you reduce a lot of things down to one thing that is objectively true but isn't really useful for everyday life.
Sure, I accept that it's possible to reduce down and argue all behaviours are selfish. Does that provide insights about the world? Nope. Does it explain human behaviour adequately, even if fundamentally accurate? "Why does inequality negatively impact inequality?" Because people are selfish?
