The state collapsing does not mean Anarchism is here. Anarchism is more than just no governments. That's what you are either failing to understand or purposely ignoring. Anarchism is itself a style of organization and ideology. Mogadishu did not have any serious Anarchist organization or Anarchist revolution. It was the result of civil war and a collapsing government. And yes, when chaos reigns warlords take over. But that is not Anarchism.
