You’re proposing group selection, which always never happens.

Evolution functions not at the level of groups, or even individuals, but genes inside of individuals.

Most of the time thinking of it as group selection at the genetic level (=individuals) does work, fortunately.

It makes technical sense that if one individual helped for example to make the rest of the colony propgate 3x faster, it would be a collective reproductive advantage

I believe it would also apply similarly under kin selection.
