True, but that all exists on a spectrum, and a law which prohibits all children from using a device because you don't want your kid using that device and they'll get bullied if they're the only one, seems a little excessive. Might as well ban expensive sneakers or shiny pokemon cards too.

The root of the issue is parents controlling how much their child uses a device, and you just cannot legislate that away. Even if it was 100% illegal, you think parents wouldn't let kids use the devices in their home if it made things easier? "Just ban it" never works, you need to incentivize alternate behavior.
