If one can make a good argument that people living forever would have too many downsides in the long run, one might reasonably not want others to live forever. This is similar to environmental policies. Even though one may not live through most downsides of current bad environmental policies, one may still want good environmental policies for the sake of their children.
Sure, I agree with that. But at that point it becomes a philosophical/ethical argument: should we allow certain people to die (or even kill them) to benefit others?
There was a time (not even that long ago) when 50% of kids died before the age of 5. I can totally imagine people saying back then that this was the "natural order of things" and that allowing every kid to live would be disastrous to the environment.
My philosophy is that we should allow (and even enable) people to live as long as they want. I wish that were not controversial, but here we are.
