The video is a little interesting, but rather disjointed. The guy doesn't seem to actually understand how emergence works. He throws in random "science" and "history" to attack government and organized religion (at least, I think that's what he was trying to do). In the first two minutes, based on the title and his introduction, it seems like he's going to try to assert that because emergence works in science and nature, it should work in communities. But then around three and a half minutes, his argument starts breaking down and making little sense.
The truth is that anarchy can actually work. But it only works in small groups and for a very short period of time. And while emergence and anarchy are related, they are also very disconnected, like trying to compare algebra to quantum physics.
