I think the idea is that, with consulting it will always be like that (vis-a-vis the travel issue), whereas a startup - if successful - will eventually result in a scenario where you can cash out, and kick back and relax. Or, if not "cash out" at least ease off on the crazy hours and what-not, and gradually transition into a "normal" business.
The assumption that startups get to that point, when most don't even come close, is (to me) more dangerous than "consulting is like selling crack."
Sure, I doubt most of us would disagree with that. Startups are risky... they're bloody f%!#kng risky... but if you succeed, you have a chance at being legitimately rich. To some people, that's a chance worth taking, to some people it isn't.
Me personally, I prefer the idea of trying to build a product company and work for the big exit, to the idea of being a consultant. But I'm not making any claim that either lifestyle is objectively better... clearly it's a personal choice.
