People tend to think of anarchism as a power vacuum. As soon as a charismatic person comes in they'll start gaining more and more following. But that's not really how it works. Anarchy is about filling that vacuum with everyone. If a decision needs to be made you bring in everyone the situation effects to make it. You start at the level of a household to neighborhood to watershed to biosphere. A charismatic wanabe tyrant will be frustrated every step they take towards getting more power.

Anarchists develop structures and agreements that discourage concentration of power. They enable people to guide their own lives and improve their communities. When violence occurs, when agreements are broken the community decided what is too be done.

All that assumes you're already there. One of the primary differences between anarchists and MLMs (Marxist Leninist Maoists) isn't necessarily their longest term goals, it's the means by which they reach them. MLMs believe that they must use the state, capitalism, and by extension coercive control in order to reach those goals. That brings the risk of capture and co-option of those structures. They've also accomplished incredible feats of human uplift so I wouldn't say their position is without merit.

Anarchists see the revolution coming about through a unity of means and ends. They create a better society by building it while the old one still stands. Their groups are horizontally organized. They create organizations to replace food production and distribution; and devlop strategies for housing distribution (squatting).
