Firstly lets be honest to ourselves, who gives kids access to alcohol? It is the parents ultimately. You cannot freely access alcohol in public without a venue offering it, but at home a parent can choose if and how much alcohol their kids have access to. Typically kids who have alcohol in public had taken it from home. There are societal morals that rightfully we consider reckless depending on how much access you give your kids to alcohol.
Now replace the word alcohol with 'the internet' in the last paragraph. The internet is already moderated for kids, they cannot buy access to it, and it is the parents responsibility to manage that. Since when did this change to being the governments job to dictate this moral and its implementation.
Parents just need the right tools to properly moderate their kids access, some of us had this from our parents decades ago with software managing content and time on the internet, I doubt these tools disappeared. The government should be facilitating programs like this. The cost would be substantially less and entirely opt-in, as it should be.
I as a parent should be able to put my kids device into a parental mode that allows me to manage what they have access to and for how long, the same way the Nintendo Switch works. I should be able to control the content my kids sees, not the government. The government can help me enable this across industry without forcing the world into an authoritarian regime using the vile of keeping kids safe.
