In light of the relativity of simultaneity, that whether A happens before or after B can depend on your reference frame, you might have to just choose a reference frame or somehow aggregate over multiple reference frames (and there may be no principled way to do so). If you just choose your own reference frame, your theory becomes agent-relative, and may lead to disagreement about what’s right between people with the same moral and empirical beliefs, except for the fact they’re choosing different reference frames.
Maybe the point was mostly illustrative, but I’d lean against using any kind of average (including mean, median, etc.) without special care for negative cases. If the average is negative, you can improve it by adding negative lives, as long as they’re better than the average.
Interesting idea!
