The article is written under the assumption - an assumption enshrined in American family law - that women are helpless and must be provided for by a man. Women lack agency and thus it is unreasonable to expect them to behave responsibly.

This is the law of the land throughout the Anglo-Saxon world (though thankfully not outside of it).

All is rather remarkable when one thinks about it. Women have the ability to jettison any child they do not want (either by killing it [!] or by post birth adoption), yet men of course are not afforded this right.
