That's a valid point. I think that kids should be able to live with experimentation possible without consequences. In practice, most teens have smartphones now and are indiscriminate in recording them. If anything changes here it will have to be the practice of recording people has to fade because it's impossible to be certain you've not got a smartphone across the room videotaping you. And in public there's no proscription on other people using their smartphones to video you as well.

I doubt I'd even notice if someone was leaning back and video recording me from their seat as I walk down the street. It would just look like a lounging person reading social media.

But yeah, I probably would prefer to have her have access to at least some private spaces without any recording so she can rest easy, but in public that's a societal shift and the smart goggles add very little. It's just inherent in computers that their processes to see also store high-fidelity. Presumably with sufficiently advanced video generation all acts will be deniable or some other such thing will occur.
