Ubasute may never have been widely practiced, but you have no idea how useful would be the fact that it could be.
When my son was little and was misbehaving, I told him that if he kept it up, his mother and I would give him back to the orphanage where we got him. He looked at me for a minute and left the room, probably to ask his mother what an orphanage was. I don't think he believed me at any point.
Damn, things were so much easier in the days of Dickens.
