Yes!
> Is it immoral for me to have 3 kids because it means exponential growth, overpopulation, famine and destruction of the Earth? If we follow the logic to its end, the only moral choice is for everyone to have not 1, not 3 but exactly 2 kids.
Limiting to 2 would cause the extinction of the human race. Some people should have 3 so that we get a sustainable level of population growth - especially people in countries where the population is declining.
(I'm not anti-emulator, I'm not even a huge fan of the categorical imperative, but this is an astonishingly weak counterargument)
