is one of the most common responses I get when I talk to people (usually liberals) about horizontal power structures. It comes down to some version of "Well, that sounds nice, but what about the bad actors?" I think the logic that follows from that fact is backwards. The standard response to this issue is to build vertical power structures. To appoint a ruling class that can supposedly "manage" the bad actors. But this ignores the obvious: vertical power structures are magnets for narcissists. They don’t neutralize those people. They empower them. They give them legitimacy and insulation from consequences. They concentrate power precisely where it’s most dangerous. Horizontal societies have always had ways of handling antisocial behavior. (Highly recommend Hierarchy in the Forest: The Evolution of Egalitarian Behavior by Christopher Boehm. He studied hundreds of forager societies, overall done amazing work.) Exile, public shaming, revocable leadership, and distributed decision-making all worked and often worked better than what we do now. Pre-civilized societies didn’t let power-hungry individuals take over. They stopped them. We used to know how to deal with bad actors. The idea of a "power vacuum" only makes sense if you believe power must be held at the top. If you diffuse power horizontally, there is no vacuum to fill. There’s just shared responsibility. That may feel unfamiliar, but it’s not impossible. We’ve done it before. Most of human history was built on it. The real question isn't whether bad actors exist. It's how we choose to deal with them. Do we build systems that make it harder for them to dominate others, or ones that practically roll out the red carpet? I think this opens up a more useful conversation.
What if we started seriously discussing tactics for dealing with domination-seeking behavior?
What mechanisms help us identify and isolate that kind of behavior without reproducing the same old coercive structures?
How do we build systems that are resilient to sabotage without falling into authoritarian logic?
I’d love to hear your guys’ thoughts.

Bad actors are going to build their vertical power structures whether you like it or not. This is the challenge liberals are posing to anarchists: if you are unwilling to build your own vertical power structure then how do you stop the bad actors from building theirs and then using it as a cudgel against you?
Exile and public shaming are tools that only work against bad actors as individuals. They do not work when the bad actors team up and form a critical mass.
In the distant past, anarchism worked because everyone knew each other and bad actors had nowhere to hide to build their power structures and grow in strength. The agricultural revolution changed all this because of food storage and the potential for an outside group to attack and steal the food. People formed power structures and developed the first militaries in order to defend their granaries and this led to the growth of large cities where people no longer had the ability to know everyone.
Militaries also showed the power of hierarchies. Making decisions by consensus is slow. A military with a formal power structure has a huge advantage in combat against an unstructured tribe of warriors. This was proven again and again as the empires of the past conquered their neighbours.
But I digress. A large city where it’s impossible to know everyone is a huge problem for anarchists who want to prevent bad actors from forming a vertical power structure and taking over. There simply is no known social tool which can combat against the formation of conspiracies and elites within a large society.
Sure they did - in the form of their own neighboring state. Then they invaded your peaceful anarchist society and you are now the great-great-great-(great....) descendant of their rape.
It sucks but you're absolutely right. Read Ursula K Le Guin's The Dispossessed. The only way anarchism worked in that story was on an entirely separate planet that everyone agreed to leave alone because it was a fucking desert and not worth conquering.
I meant distant past before statehood was even a thing. That was before agriculture when all people lived in nomadic tribes. There were no neighbouring states because no one had fixed territories. Groups still fought among each other as they tracked the movement of migratory herds (mobile food supply) but there were no raids on granaries because there were no granaries yet.
The first agricultural societies had a really bad time. Their nutrition was extremely poor compared to the meat-rich diets of nomads. The nomads with their superior health and mobility had easy pickings on the crude granaries and poor defences of early farming villages. Statehood began when those villages began to work together and start their own militaries which led to specialized soldiers for the first time (as opposed to nomadic warriors who fought but also hunted and parented and everything else their tribe needed them to do).
