Or we could socialize healthcare for all then treat gene edits like this as we do vaccination. We offer only those edits which would prevent chronic and termination disorders in life but leave anything else that's merely socially undesirable like neuroatypic "disorders." I know this suggestion isn't bullet proof, but it's better than letting crackpots do this in the shadowy corners of society creating all kinds of changes which lead to more suffering for the people that would bear these gene edits (I can imagine there being some weirdo rich couples that wouldn't mind turning their future kids into Nosferatus despite the adverse social impact that would have on them).
