I suppose that people who actively do not want to have kids should not have kids. Their hypothetical kids won't be happy and well-developed, but instead always feel that they are an undesired burden.
Instead, people who like having kids should have more kids. This would proliferate a healthy culture that sees kids as a source of happiness, not a burden of misery taken out of necessity.

To make this work you need some kind of cross-subsidy (e.g. large child tax credit), because having a larger number of kids requires the means as well as the will and the people willing to do it aren't all billionaires.
But then we do essentially the opposite and drive up housing prices when larger families need more house. Higher housing prices are essentially a transfer from young and future families to retirees.
I am not convinced that is true. Once you actually have kids it changes your outlook too dramatically. Someone who does not want to have kids before they have a kid, will almost certainly love any kid they actually have.
I doubt there is a correlation between kids being wanted before birth and their likelihood of entering foster care. People who do not want kids do nkt have them.
