And my problem with such claims is that it seems like you're actually just proposing another kind of government; a local and decentralized one. After all a government is just an agreement between a set of people to organize affairs of mutual interest, right?
Would it be correct to say that anarchists (in general or the left kind) actually prefers several smaller societies rather than one big central one?
Also one could argue (as you kinda did) that once upon a time there were only such tribal societies, and that the societies we see today have evolved from those. So if you (with the belief you once held) argue that we should revert to such a system, how would you propose to prevent the inevitable "degradation" to the current system?
