Tyler complains that humans have lost value in society, yet the participants in project mayhem are known only bu number. What is wrong with his plan to change the world?

This is a paradox of sorts. I think that Tyler was trying to start a movement where men can discover themselves but in doing so they lose their identity to the movement itself. Their use of violence to change the world results in violence becoming the change rather than any meaningful alteration of society. I understand that Tyler wants to tear the world apart in order to start over but violence becomes his only means of discovery and enlightenment: this is problematic.
