This already is what happens with sexual selection. That is the purpose of sexual selection from the point of view of genetic integrity. People are designing their babies every time they have sex. There's huge amounts of money involved there too. And like how do I know the geneticist isn't slipping his own in-born DNA in my place, like that fertility doctor did or that criminal inseminator who broke into poorly-guarded sperm banks and substituted his sperm for that of astronauts with Nobel Prizes? Had like 660 kids that way. Like there good reasons to do this are, OK genetic malformation, ie osteogenesis imperfecta, that's a SNIP, totally. Or you were raped, want to punish that rapist by making the egg have even less genes in common with him than it would ordinarily, making his rape counterproductive genetically. Another good reason, defensible. Or you want to protect rare alleles, considering weaknesses to be strengths, this is like a left-handed man marrying a left-handed woman, or freckles (I think something about freckles make children hate them til they're 19, rare exceptions, not even the iconic Lindsay Lohan accepted her own freckles). Preserving their identity and diversity. Don't pass laws as much as using judgment to decide, individually and collectively, what the future will be. Talk and think instead of setting up magic words for lawyers to copy-paste--an isomorphic problem to genetic design. No fucking blind copy-paste, don't use copy-paste with your copy paste to copy-paste yourself.
