I don't allow unrestricted access to the internet for my kids and they aren't allowed screens in any room except where others may see them and their screens all the time. Yes, it is friction and not perfection. The internet is a Victorian-era cesspool with raw sewage and dysentery everywhere. They'll have to learn how to not contract cholera as they grow up, but I also don't let them play with firearms or dabble with black-tar heroin.
