You just defined the value and utility of it thus it is valuable whether he dies or not. Your argument is like saying that understanding cold fusion has no value because no one has communicated a valuable understanding of cold fusion. It might not be possible but if you by your own definition figure out how to do cold fusion then that is a valuable insight, whether or not it comes to fruition or the person dies. Insights cannot not be valuable, they don't have to be implemented to be valuable which is easily demonstrated by a simple thought experiment. If you had a time machine and could go back in time on that submarine right after he gets the idea on how to do it, extract that information and leave before he dies, would that be valuable? Of course it would. Getting an insight in the shower or getting an insight on drugs/mushrooms doesn't change the value of the insight whether it gets implemented or not.
