As has been pointed out, it would be easy to grab someone else's children in order to fraudulently sign up for government checks. In my own city, there was a massive fraud operation of mothers claiming to run (federally subsidized) day-care facilities and listing each other's kids as the attendees. It was all on paper of course; no kids were being looked after. That's the type of abuse that will always occur and needs to be curbed in some way.
