What made the book "Handmaiden's Tale" so frightening to me was how plausible it was. Limiting a resource, like fertile women in the aforementioned book, didn't make it more freely shared. It made those in power try more desperately to control it.

The limit on health care and medicines isn't the sole driver toward war and tyranny. It's about power and control.

Limiting the human lifespan doesn't automatically mean charity and the impulse to share resources. With where the world is today, I think it would be the opposite.
