My opponent's case boils down to this: phones cause distraction, distraction lowers grades. But that's an argument about unsupervised use, not ownership. A device can be locked to calls, maps, and school apps, or kept in a drawer until homework is done. The question isn't whether kids can misuse a phone, it's whether a blanket ban is the right tool. It isn't, because it also blocks safety uses like medical alerts and reaching a parent. Rules and parental controls target the actual problem; a ban just avoids it.
