Okay, a General Secretary neuron in the brain then. Or all different kinds of living systems that secure a collective security of all members, none of which have a chain of command to one cell or individual in the center, making decisions on behalf of the whole.

Distributed decision-making systems are far more common in nature, in networks, and in the human experience. The only reason why it has not seemed so for the latter is because during a specific period, it was possible for centralized societies to gain leverage to wipe out non-centralized societies.

I don't consider myself anti-Leninist at all. I am fully on board with a vanguard party for the proletariat, as long as that vanguard party recognizes the congruity that monarchy and capitalism have with positioning individuals as absolute heads (or kingpins, or chokepoints) of command chains, and deliberately avoids the pitfalls of that model. That doesn't mean scrapping the concept of authority; the only thing that needs to go is authority that encompasses all domains and that positions people in rigidly defined strata, instead of specialized roles that are not ranked against each other.
