I agree with everything you've written, but from a personal mental health perspective, it makes sense for most of the population to accept it. That is, until it's certain to be fixed in their lifetime.
That's a self-defeating proposition; the more people accept it, the less likely it is to get fixed within their lifetime. The more people object to it (and do something about that), and the more broad cultural acceptance exists for a solution, the more likely it is to get fixed. Imagine a world where all the memes, mindsets, and casual empty aphorisms about death didn't exist; how much more urgently might people treat the problem in that world?
That said, it's also the kind of concept that needs some amount of introduction and background, to avoid "future shock".
