From what I recall of the book, one of the major points is that, as you relinquish control over your decisions, you also
- dissociate from responsibility over them (the dice made me do it),
- feel increasingly at ease with that lack of volition,
- start to replace that kind of decision-making with choosing ever-more risky/thrill-seeking/repugnant possibilities for the dice
I never read it as endorsing the premise; thinking it does so seems to me to be like thinking Trainspotting glorifies drug-use.
