Are you talking to Scruton, or…?
No offense, but is it just me or do traditionalists often write in a similar style? Some things are always mentioned: familial relations; mythological figures; a few vices…
Anyway, user, we're well aware, and in agreement, that the erosion of community is a massive problem. It comes up constantly in threads about alienation. Communities, even those traditional without being regressive such as the one you describe, are not only fine, but necessary, tho they can assume other, more modern forms, such as neighborhood associations. I know people whose dream is to bug off and live in a tiny, traditional seaside village in a poor but peaceful country. All power to them, I say.
But you're making a few mistakes here. One, I admit, I can't know if it's lack of awareness of it or you just ommitted it, but the greatest destroyer of institutions, including communities, is capitalism. Not even Stalin deliberate steamrolling over many "old ways of living" killed as many as the capitalist system does just by existing and growing.
Another is saying Scruton provides examples. They're not examples because it's not at all established they were based or reality. I mean, authority by merit is obviously real (Lenin reached the top of his party on sheer strength of argumentation and rationale), but something like these benevolent figures in small communities of times past seem to naturally have existed, but effectively, they might, for all I know, be the old literary equivalent of the Manic Pixie Dream Girl. An example would be a history book or a study, not fiction.
Also is treating "authority as dogma being transcribed in a one-dimensional process or violence when this is refused" (I assume you mean the usual political process in a State) and the numerically smaller community with its informal authority figures cannot co-exist. They can, in both constructive or destructive ways. The former might be, for example, scientists or experts in a topic so their opinion doesn't require an office in order to be more easily heard. The latter, any poor country without rule of law.
Lastly, like I said, some older forms of community are perfectly fine, but some are… less than humane, let's say. And there's always someone wanting to revive the latter. So some forms of community could return without a problem, but many – probably the vast majority throughout history, if I had to guess – is better off buried in the past.
