I am an omnivore, never tried vegan diet so can't say whether it would work for me. I am not defending it either. Just questioning why you are passing swooping generalizations. There is as much evidence that veganism works as much as there is for Paleo. Lack of pure vegan culture is not an indicative that veganism has no merit as a good/bad nutrition.

I grew up eating a very SAD, cereals and many processed carbs, little to no veg, and conventional fruits and meats. I made the switch to vegan at 17--i attributed my veganism for ridding me of my exercise-induced asthma, but then realized i had moved out with my boyfriend at the time, away from my parents house where three people smoked constantly. I didn't lose weight as a vegan, I actually lost weight eating meat--but I felt awful. BUT the diet I lost weight on was incredibly low-fat. I had nightmares every night that I thought were caused by eating meat, but I just realized, perhaps it was the lack of fat that caused that. I felt better returning to being a vegetarian, as I was eating eggs. This continued until I tried a raw diet for a few months. then, went back to cooked vegan, then vegetarian, then pescatarian--i ALWAYS felt better when I included eggs and fish, but I was in serious denial and felt ashamed that I couldn't be a vegan. After being "successful" with raw food for three months, returned to cooked food AGAIN and continued the flip-flopping guilt ridden vegan trials.

And now, I could NEVER imagine going back to being vegan.
I really wonder though, that if I had made the switch from SAD to primal if I would have felt the same. I didn't even consider primal an option, though, because my reason for becoming vegan was solely based on an emotional response to factory farmed videos. when I made the switch to vegan, I don't really remember any health issues. Mostly heartburn after eating and the asthma, but only when i exercised. I was also very much overweight, probably obese for my height/age.
