I was implicitly assuming a closed system here, to be clear.
The trick that makes the game locally positive sum is that the earth isn’t a closed system relative to the sun, and when I said globally I was referring to the entire accessible universe.
Thinking about that though, I now think this is way less relevant except on extremely long timescales, but the future may be dominated by very long-term people, so this does matter again.
