I do not disagree with any of this, I was hoping it was implied by my original comment that this would be necessary.

This all needs to be modulated by the knowledge that some children benefit immensely from being able to hide parts of their lives from their parents, parts that their parents would disagree with greatly.

The clearest example is LGBTQ kids who want to talk to other LGBTQ kids, or enjoy LGBTQ content, without fundamentalist or just homophobic/transphobic parents finding out. Children of fundamentalist or cult members who want an escape from the cult are another common category.
