If the end goal is to give wanting parents children, there is already a huge excess of children without parents in the world.
I'm not necessarily arguing in favor of creating more children, but your implied "just adopt" doesn't meet most potential parents' desires.
Apart from true medical conditions, I am always a fan of "do it if you can". What better way to advance the species?
