It is an incredible breakthrough and if it prevents disease then all well and good, but are our Administrative Systems set up to handle such an arrangement?
My daughter doesn't know why we have archaic laws around seatbelts either, but she's 3.
The seatbelt laws are not archaic by any meaning of the word, and they can be justified with rational arguments.
Care to try doing the same for family thing? Aside from tradition.
(I'm not supporting the argument, just saying that it's not hard to come up with a plausible rational one)
The modern nuclear family is, well, modern. Children were collectively raised in most cultures. (Certainly almost all that gained prominence.)
(genuine questions)
The earliest evidence for nuclear families is in Germany, going back 3,000+ BCE [1]. We next seem it gain prominence in 13th-century England [2]. Otherwise, the default for non-nomadic societies was kin (extended family) or community oriented childrearing. Similar to what we see in traditional family structures in South America, Southern Europe and Asia.
> could also see the argument that parental role is diminished in modern society with the outsourcing to public schools
It would be difficult to make this argument given the primacy of parents in public schooling compared with e.g. their diminished role in kin- or community-based childrearing systems.
