> Society gains massively from future workers/tax payers

It seems to me that, all other things equal, future workers/tax payers will lead to economic increases proportional to their costs.

A reasonable forward looking plan / budget scales with the population size. Therefore there would be no need for these special one off exceptions and nudges.

All these little bandaids add up to complexity that necessitates more bandaids.

This only applies in a steady state.

If your populations shrinks quickly, you end up needing to run the infrastructure (and elder care!) for a whole country with too few working-age people.

This is a massive problem, and some incentive complexity to avoid it is certainly worth it.
