Well, we're seeing a case where a type of parenting is viewed as neglectful, so we're adding a law to enshrine it's legality in the face of changing cultural norms among certain sets of the population.

This is not the same as "Anything not enshrined in law is unauthorized."

This seems like a matter of the legislature reining in law-enforcement whose interpretations have become overly broad, something legislatures (and Congress) also sometimes does to the judicial system.

I agree that it can be cast in an awkward light but it's not uncommon.
