I don't think we should be thinking about this from a psychological perspective but instead a sociological one. Yes individuals can disconnect and do whatever they need to assuming adequate resources but that's beside the point.
If you think of people as boxes with inputs and outputs I think it's very worth understanding how social media impacts those boxes and what the long term affects are.
Has nothing to do with being a victim. Just if you press this button on every box does something desirable for society happen? Or something negative? Or we can't tell still?
And if it is negative then do we as a society want regulations to reduce the impact?
