> One person living forever is not really be a big deal. But everyone?

I think any society that is capable of letting humans live forever — on the scales being discussed — would probably be virtualizing sentiences instead of relying on wasteful fleshy bodies.

Living via a human body would be a novelty experience, a vacation, a limiting of capabilities and senses.

Essentially, I think your point would be mostly mute by the time we develop true immortality.
