Well, I'd argue that the residents of BNW weren't living in bliss- if they were, they wouldn't need violent passion surrogates or pregnancy surrogates. There's, something missing in their world that they have to substitute for, and they Know that they're substituting for it, even though they may not understand exactly what it is that is being substituted for.

The thing is that what you don't know Can hurt you, all too often. And just because you don't know to be afraid of something doesn't mean that it can't bother you or hurt you. Ignorance is bliss only in the very temporary sense.
