I disagree with the way you are presenting it, but let me take a different stab at re-summarizing your post:
Humanity's legacy will be measured as a group effort, rather than any individual input. At its root, this is because individuals will die and have relatively short lifespans compared to the collective human species.
I'd let the implications start rolling in from that point instead.
