Pigou Club for Children?
If I'm a Green Puritan it makes sense. Children impose a negative environmental externality. Therefore, the social cost of a child is greater than the private cost. So we draw our little externality graph, and pick Q*, and tax each additional child for n >2 to get the "socially optimal" number of children. With moral and economic understanding like this, I wouldn't be surprised to see it suggested at some point.
