This. Even if you could conceivably account for every feasible epigenetic difference possible in every conceivable genetically distinct human, I'm not sure what the point is. Twins are still different people with different experiences and personalities even if they are nearly genetically (and epigenetically - at least at first) identical. I feel like the spirit of OPs post is humans in a post scarcity society have a duty to bring into existence every feasible distinct human experience. But this is impossible because DNA and even epigenetics does not encompass all that makes a person unique and distinct.
