I'm not sure I really disagree with your points, but maybe I can supply a counterpoint.

We don't value being alive just for the act of breathing, there has to be more to it than that. As Shelby Browne said, "A ship is safe in the harbor, but that's not what ships are for". Getting anything out of life that makes it worthwhile and maybe worth preserving, is going to entail some risk in itself. The alternative is agoraphobia, which builds on itself until the victim is afraid to step out of his room. He may be very safe- but he's wasting his life anyway.

There are always going to be some aspects of the subject that are more interesting to people than they are really important, and some that are much more important than they are interesting to most people... but, if you don't let people indulge their interests, they'll just go do something else and forget about the whole thing. Surely that's worse than a less-than-survival-optimum balance of subjects?
