Yes I agree it is required to a certain extend however at the same time I think the socially acceptable level is usually too much to the parents control of the child. The falloff could be quite strong in my opinion. It is a difficult balance but usually parents or adjacent persons don't even realize privacy violations are happening. It is a real problem for kids (and people trying to help them) in difficult and abusive situations.

I have seen famous influencer (parents) commonly say things like "If you live in my house I can go through your room any time I please.". I understand the sentiment and some kids and situations require that, however I think openly incentivizing others to do so or normalizing that is not right. Especially knowing that it can make reaching out of abused kids much more difficult.
