You say that like addiction is just something that can be taught by parents to overcome. You can attempt to teach your kids to "just say now", but they are kids and are going to rebel against anything they are told they can't do. That's just part of being a kid. Once they do it and become addicted, telling them no is just a useless concept.

Part of the problem of laying it at the parent's feet is that there's a much larger than zero chance the parent(s) also shows addictive behavior. To quote the after school special, "I learned it from watching you, all right?" I still go back to the fact that the addictive thing is being intentionally manipulated to increase the addictive properties. It is not natural. It is the thing in and of itself that is the problem.

I don't know of any viable rehab potential for social media. I can only imagine the relapse potential would be closer to 100% than for any other drug.

This puts parents back in control of what their kids are consuming. Without laws like this, it’s extremely difficult for parents to supervise and control their children’s media consumption.
