There's risk either way -- opportunity cost if you don't take the plunge.
I feel like ux-app did it well, too, though, by mitigating the risk since he was able to take the 6-month leave. If a person can do something like this, or gain some free time (Fridays off, work from home, etc) to at least build out a first version of a product to market before quitting.... it's probably a good way to go, too.
Of course, not everyone has that opportunity. If you hate your job and want to work for yourself, and your boss won't let you do what ux-app's boss did.... then yes, quit your job and go for it! Like you said, moron4hire -- worst case scenario? You go find another job and you're right back where you started.
