Oof, I need to go to bed, but I have a bit of a beef with "Tribal" being used synonymously with "Pre-Industrial" or "Xenophobic" or "Willfully Ignorant Of Ideas That Don't Agree With Preconceptions Held By Their Clique", despite understanding why people use "Tribal" to mean these things. The same goes for how people seem to be talking in kneejerk reflex reactions to the word "anarchy/anarchism", as though it meant martial law or uber-libertarian throwing people to the wolves. I think crossed definitions are conflating these ideas unnecessarily, and is undermining some good points that the idea of the Tribe-as-a-Society or that Pre-Governmental and Non-Centralized-Governmental Societies make within this discussion.
RE the Tribe:
It's easy to conflate the fact that decentralized or pre-governmental societies predated industry with them being somehow innately preindustrial, technophobic, or somehow incapable of science or complex manufacturing. But dude, tribes didn't just not invent or improve on technologies, medicine, language, tools, manufacturing processes, military strategy, philosophy and other intellectual pursuits, etc. Ditto for tribes being thought of as a Xenophobic or Cliquish thing; this was a product of a time period, and not a social structure, and it's common to many empires, city-states, and tribes alike; having existed in an era when people lacked common language to communicate appreciably, a sufficiently detailed or well-informed history to look back and infer from, and other abilities to see the humanity in the other groups of Humans in the world leads people to reject them and their ways due to their alienness and lack of an understandable reason why they are or do things that way. Note: We're not immune to this even now.
RE Anarchy:
Yes, laws are awesome at codifying predictable punishments to discourage specific behaviors, which is helpful in preventing those behaviors before they happen. Laws are the training wheels of pro-social behavior, and a codex for proper and ethical behavior, in a way nearly identical to how Religion functions; the main difference is that while one appeals to a cosmic authority or force that can hold you accountable in some superhuman way if you defy it's codified ethics, laws appeal to a realworld authority that can kill or imprison or exile you for the same.
Law, also much like religion, is just a codex of one or more persons' interpretation of this more-or-less shared Human Social Nature, interpreted into a set of rules to support it, and over time extended to deal with modern situations and increasingly specific cases. However, it's all still emergent from Human Nature; even the American Justice System with all it's codification and letter-of-the-law intent, hangs on a judge and jury of citizens deciding whether they liked something that someone did or not, and whether they seem trustworthy, innocent, repentant, etc. We're still counting on peer-to-peer ethical judgements to reform troublemakers or remove them from our given culture; the only difference is someone just designed a system to pick who does the ethical judgement on behalf of everyone else in their culture (because it's impractical with this population size to have every citizen weigh in on every legal case), and they enforce this with other people selected to hold dangerous weapons and imprison or execute them as necessary.
Order doesn't require law. It just requires tools like Communication that enable people to hold other people accountable for being antisocial, or working against the collective, whether that's a tribe, a nation, a culture, a species, or an entire planet full of various lifeforms. Law and Religion helped us codify and maintain order in a sustainable way, but in an era when we have the means to organize and communicate and share resources and know on a global scale, there's real room for us to adopt a decentralized approach to self-governance, or a modern brand of non-governmental egalitarianism.
