Upholding a law is a waste of time if it is a bad law in the first place.

I have been dubious for more than 20 years, over the wisdom of persons with degrees in sociology and very little experience of life, making decisions that can affect the rest of the lives of their 'clients'.
Social justice is achieved through wisdom and experience, and not by applying theories learned in text books.
The government has no place in family relations.
How can a legal statute fit all sizes in something as personal as that?
I am not social worker bashing, I am questioning the need for them in this role in the first place.
As far as familial relationships are concerned, there must be a better way?
