Yes and if elites are inevitable, then it follows that inevitably they will organise themselves to (A) protect their elite status and (B) benefit from their elite status.

Thus the distinction you draw between natural and political elites is kind of arbitrary. They are elite in comparison to others in the community who look up to them/defer to them/acknowledge their authority. So if one community member does that voluntarily and another party does not, in practical terms it makes no difference - you can ignore the Godfather’s edict and his authority the same as you can be a sovcit and deny the cops authority; you’re still flesh and bone and that bullet won’t discriminate.

Anyway I think you’d find that book interesting, just to pull together some concepts about how elites are going to act regardless of voluntary associations or not.
