But it is being enforced [unconstitutionally] to prohibit an [unlicensed] family from living together

I disagree with you. Fornication is not protected by the US Constitution.

There is nothing unusual here. This ordinance is designed to prevent home owners from renting rooms, turning their homes into cheap tenement houses.

Fornication is not the issue.
If these townspeople don't like unmarried couples w/children living together, it they who should move, -- into a planned community where such restrictive covenants are legal.
The federal system guarantees that there will be plenty of space available for these communitarian people, since federalism protects true diversity among Americans.
