In an ideal world your entire clan would occupy a sizable piece of land. You would spend your days teaching your grandkids how to bring whatever products your clan makes from conception all the way to market. Your "social security" would be 5 generations of your people working together. No one would ever go hungry or without shelter. Your police would be a militia of your own brethren. You would govern no one but your own kin, and no one who is not your kin would ever govern you.

It sounds farfetched in the context of the world as we know it, but this was the system before Rome imposed its law on western civilization and though we still have some cultural memory of the moral character of the civilizations we used to be (concepts like freedom, honor, integrity) before being conquered by the Roman system and the Abrahamic religion -- which were not the source of our moral character or cultural memory. There was a deliberate effort to perpetrate a history that would vilify (and literally invert) the swastika (a symbol unifying Scythian/Gothic tribalism) and the word Aryan (and so burying an Arian Christianity that was truer to what Jesus taught than the weaponized Christianity of Roman Catholicism) all in one final swoop before modernization and the information age would be allowed to progress any further -- and that was by design, I think.

Sorry, you asked a simple question an I gave you a weird answer.

In the real world that we're stuck in, Social Security is necessary. You don't have a clan or land or a future, just a present need to eat and survive as an isolated citizen of a paper empire that doesn't give a fuck about you beyond the optics of you starving after a lifetime of citizenship and work while they eat caviar and steak off a silver plate with their uncalloused soft hands.
