They didn't say "Nobody should be allowed to have more than two children". They simply have an opinion that people shouldn't, purposefully, have more than two children. Seems reasonable to me.

Yes, thank you. I'm not Mao. People should choose to have either no children Or ideally one or two children And not no children.

Ideally, we as a society should support people who choose to have one or two children, prioritizing these families over people who have half a dozen or more children. But that's because in my opinion people who have dozens of children have something wrong in their heads. If you choose to have a dozen children, you better be able to afford to raise them all on your own dime.

That being said, I really dislike means testing of any kind so I'd be ok with a social safety net for the wackos and their unfortunate children.
