Not a lack of tools. A lack of the right one. Every parental control, every data plan, every screen time app works on one device at a time. None of them work at the level a household actually lives at.
Every family pays for broadband and mobile data, but no dashboard shows how it is actually consumed across their devices. The bill arrives each month, undifferentiated. Nobody can see what is going where, or why.
This invisibility is not accidental. Platforms are commercially engineered to exploit it, using variable reward mechanisms designed to trigger compulsive scrolling. That design is particularly effective on adolescent brains still developing the impulse regulation systems adults rely on.
Every restriction placed on a child is bypassed the moment they pick up a different screen: a tablet, a games console, a sibling's phone. Parental controls are set device by device, which means they only ever work until the child walks to another room.
This is the device-switching bypass. It is the reason every existing tool for managing a child's screen time eventually fails, no matter how well designed, and it is the same gap that every age-restriction law runs into once it reaches enforcement.
Working from home professionals and home schooling families have no way to protect their internet allocation from competing with passive entertainment consumption, because all of it draws from the same undifferentiated, invisible pool.
A video call can compete for bandwidth with a teenager's stream in the next room, and nobody in the household can see that trade-off happening, let alone manage it.
Governments in several countries are independently reaching for the same policy: restrict social media access below a certain age. Each is running into the same enforcement problem, because the tools available today all work at the device or platform level, not the household level.
Enforcing an under-16 social media account ban since December 2025. Nearly five million underage accounts have been removed, but regulators report children continuing to create new accounts and slip past age checks.
The European Commission set out age-based access levels this month, no social media under 13, restricted access from 13 to 15, with the plan still to go through Parliament and Council.
The Delhi High Court is pressing the central government to decide on guidelines restricting access for under-13s and regulating platforms for the 13 to 16 age group.
Government has set out its own proposed restrictions for under-16s, alongside curfew-style limits for older teenagers, following a broadly similar shape to Australia's approach.
None of these frameworks currently reach below the platform or device level. A rule enforced on one screen is not enforced at all once a second screen is available. Structural enforcement at the household account level is what closes that gap, in any of these jurisdictions or the next one to legislate.
