Exactly. This boils down to a political primacy issue. Which has primacy, the individual or the group?  Eternalism says the individual has primacy. Satan's plan wanted collective salvation.

Doesn't individual achievement contribute to the collective well being? What drives the collective well being when the individual has surrendered their right to prioritize achievement?

For anyone who has gone through the Eternalism politics course (http://www.christianeternalism.org/politics.html) the words "collective well-being" should be a big red flag warning of what is being promoted.

In the Netherlands, I’d learned that a society could prioritize collective well-being over individual achievement. That “enough” could be a destination, not just a pit stop on the way to “more.”
