I mean "Stop at two" isn't a particularly awful policy, yet that is sufficient to curtail population growth.

I doubt it even needs to be a policy in many countries - I don't know many people with more than two kids.

Agreed. Two even three. The issue is when most people go over that. It's not usually because they want to but because they don't have the means or options to control their family's growth.
