I've read that German society, for example, is largely based on contracts between the family unit and the state. Sweden, as a contrast, is largely based on contracts between individuals and the state.
As an example, Germany treats a married couple as a fiscal unit, Sweden abolished joint taxation in the 70s. Swedish parental leave is allocated per individual, and is mostly non-transferable.
In a lot of ways, individualism is produced by state contract in Sweden.
e.g. The claim: Planes are a very safe way to travel.
Followed by someone jumping up to say: I know a person who was injured in a rough landing.
Note I'm not claiming either the individual or family is the atomic unit here just pointing out that your contribution doesn't contradict or even narrow the argument.
∀x(X(x)⟹(Y(x))
and then they make it their mission to find the falsifying x sub 0 example.
More commonly we see things like,
A: "I went to work today"
B: "One time I was on my way to work but I slipped on the ice in my driveway and ended up in the ER with a broken leg instead"
A: "Your broken leg does not disprove that I went to work today..."
Where A is trying to relive their glory days on Reddit where such a retort would have been considered funny, but thankfully most HN accounts know better than to think that is still funny, or that it was ever considered funny on HN. This thread being illustrative of one such exception, of course.
Individual is part of nuclear family, nuclear family is part of extended family, extended family is part of tribe, etc. When one part is in need, the others jump in to help.
You come across the term a lot in old genealogy books. For instance in "The History and Genealogy of the Prentice, Or Prentiss Family" (from 1883) contains:
> All his immediate family, himself, wives, and children, are dead.

Ancient egypt? Roman times? Medieval times? Byzantine times? Pre-colonial Philippines? Pre-colonial America?
I think it may have started in the late 1800s at the earliest. I would need a bit more evidence to be convinced that your model of individual to nuclear to extended etc has been a thing longer than a few centuries, vs the vast majority of human life experience being in nomadic hunter-gathering, villages, farmland, and walled city-states. We just had clans which were all our family. A fellow villager wasn't much different than a cousin. The individual and nuclear family, not so much a thing.

Probably you're focusing too much on the parent comment's mention of nuclear family. Even that, despite only being named a few decades ago, is likely to exist to some extent. Even in some ancient tribe or village, most people would favour their spouse (or equivalent) or child over a cousin or niece/nephew if some dispute formed. That hardly seems controversial.
I suspect you're actually talking about the current western/american conception of family (fair!) but it doesn't make sense to ignore this obvious miscommunication.
in which they lived in families, extended families and tribes as the primary units. I didn't understand your argument at all.
