And I assume that all the problems stemming from the increasing life expectancy are also positive sum? And planning to do so based upon no established scientific grounds by making the younger population contribute by submitting to a non-zero risk procedure.

You can look at it every way you want, maintaining the elderly population is certainly not a logically positive thing in a ressource-constrained environment. And by ressource, I don't mean blood. That we have morals (which is good) does not make it good from a general logical point of view disregarding social ties.

Or are you just saying that there are too many people, and think we should have fewer?
