A similar form of middle ground without touching the app/web level may be to enable device parental controls by default on new Phone and Tablet purchases and rationing its removal with some kind of privacy-preserving ID hashing protocol that's also rate-limited per ID. 90% of the problem is mobile device ease related, it doesn't need to extend to PCs. Still a ton of burdensome consequences. But really, the best policy would be constant social and educational emphasis on device parental control feature awareness - similar to drunk driving campaigns. Get parents and guardians in the habit of taking 15 min to set up basic parental controls BEFORE handing devices to kids. Rather than the all-too-common mess of reacting to a problem by taking the kids phone or making them manually show everything after the damage is already done. Maybe also compel device manufacturers to incorporate a first-time-setup flow that has a specific soft ask of "Will this device be given to or borrowed by a child?" that then handholds the owner through setting up controls.
