Traditionally, and even mentioned in this terribly written article, prepubescent child marriage as was popular in that area is more about managing abject poverty then anything else.

Very different from what you see in the west with the laws being more that there is an avenue to marriage for teens that end up becoming parents.

Banning it typically either results in it going underground, by a different name, or those that would have been married off ending up in an even worse situation unless there is a significant effort to offset the cost to families with daughters.

Hopefully they have accounted for this sufficiently add the bad article is just bad.
