If distraction is the real problem, taking the phone away just hides it. A kid who never owns a smartphone doesn't learn to ignore notifications during homework, charge it outside the bedroom, or ask before downloading an app. My opponent is right that careless phone use can hurt exam scores, but that's an argument for rules, not a ban. Picture a family with a homework-first routine and a kitchen charging cable: same phone, very different outcome. Banning ownership also removes the safety lifeline when a bus breaks down. Teach limits, keep the lifeline.
