Privacy is a form of security though (security for your own thoughts and actions in the own home, and in, on, and near your person). At the very least it is a domain that strongly overlaps with security.

And good security is what gives you the safety to be free.

If you want to sacrifice freedom for security, you might end up putting the cart before the horse.

And of course sacrificing privacy for security is at best balancing 2 different kinds of security. You're not necessarily gaining security.

In this case it means that there's no guarantee that children will actually netto be safer if people can scan private communications.
