At some point many years ago I read that the family, not the individual, is the building block of society. It might have been Chesterton or Friedman as I read a lot of both when I was young. It certainly is a lot easier to hold the line when you have a squad of half a dozen to a dozen with you (wife/husband/children/brothers/sisters/uncles etc). If the state is there, then you are fortunate, but I wouldn't want to count on it myself.
I know several families who are absolutely not a building block of society. Some not by choice.
This is how it has always been throughout history (and still is in most parts of the world).
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.
It's cultural.
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.
