The problem is that I just don't see any overarching goals that he wants for society other than for people to cut loose, get back to basics, and live. These things just scream SP.Tyler Durden is INFJ - social revolutionaries (good and bad) would consistently be INFJ's.
ESTP's aren't worldview dominant (i.e. wouldn't possess that strength of hatred of society) and aren't extremists - Ni/Fe/Ti/Se sees the flaws in society and goes about bringing his vision to reality (starting at Ni to finishing at Se).
I think you and Tony are giving Tyler too much credit. I think he made a lot of decisions on sheer impulse that just happened to work out for him. Remember, SPs have a way with words they can spout off a lot of things that sound deep, but really aren't. That's what I see Tyler's "philosophy" as mostly being: things that sound good but don't have a lot of depth to them.
