> Why? It’s repressive if done to cap a natively-growing population, since that means government controlling reproduction (à la one-child policy).

There's a point where caping even natively growing population is actually the right move.

There's plenty of overpopulated shitholes (Mumbai, Dhaka, Cairo, Bangladesh, etc) where it would have been an absolute blessing if government was controlling reproduction or put a population cap in place.

If you think capping population is wrong, go visit Dhaka, I highly recommend it.

If you're still on the fence after visiting Dhaka, you're beyond saving.
