Warlords are able to do that because they already start from a position of power, exploiting others and making them act against their own interests. This is one of the core problems “fixed” by anarchism.

Does this mean this will never ever ever happen in an anarchist society? No, there will always be threats. But disregarding anarchism entirely just because it can’t fix something that is fundamentally unfixable hardly seems reasonable or fair.

Good thing that can’t happen in a liberal democracy or we’d be in trouble about now.

I don’t understand anarchy well, or really any political theory, but if there wasn’t a state to have a monopoly on violence, couldn’t we just kill the people trying to hog resources and control people? Right now it’s illegal for us to harm people who are very clearly and directly harming others, and I think our situation would be improved greatly if certain people in power were dead, and if everyone could see that their harmful actions are what caused them to be targeted.
