So how does this work in practice? Once the population reaches 10M, people can't have kids?

I'm going to guess that having too many kids would be a happy problem for them (and most gentrified Western societies)

Based on Switzerland’s total fertility rate of 1.3, the population increases only due to immigration, so controlling the flow of immigration is all that would need to happen.
