Frankly I'm scared by governments and corporations going "papers, please" for people to be allowed to access the Internet. On top of endangering privacy by tying pseudonymous online interactions to real-life ID and biometrics, attempts to block under-18 people from finding information or interacting online will only amplify how society regards them as not having rights. This will isolate people (especially gay and trans teens) living with abusive parents from finding support networks, and prevent them from
learning (by talking to friends in different situations) that being beaten or emotionally put down by parents is abusive and traumatizing.
I know all too well that when you grow up you're psychologically wired to assume that the way the parents treated you is normal, and if they harmed you then you deserve to be hurt. I've made friends with and assisted many teens and young adults in unsafe living situations (and talked to people who grew up in fundamentalist religions and cults), and they're dependent on online support networks to recognize and cope with abuse, get advice, and seek help in dangerous situations.
