I agree with you but the inevitable counter argument is that not letting kids have unfettered access to screens and the internet is impractical to the point of comedy. I personally do not buy this argument, and although I do not have a child, my sister has kept my nephew screen-free so far and he's well at the age where kids start to use them independently. What does he do instead? He reads, he plays games (he's allowed some supervised access to video games), he plays sports. Stuff kids used to do and were totally fine.

The other argument is that this makes kids socially isolated from their peers, because they all have and use these devices. If that truly is the case there definitely still is a way to monitor your kids device and internet consumption without giving them free-reign. There are internet safety settings for parents on every device out there. Kids are perfectly capable of communicating with each other through a variety of mediums, they don't need tiktok (or whatever app is the trendy one of the decade).

The last argument, when you present the former argument, is that kids are clever and will find a way to get around controls. Yea, no shit, that's what kids do. Your role as a parent is to monitor that and teach/correct them.
