This essay extends one anecdote involving 16+ year old teenagers to the unsupported conclusion that kids should have phones and those who wish to restrict that are all wealthy 1% right wing authoritarians. Then with the personal note it seems clear that the core of the essay stems from the author's own personal trauma/experience.
I don't disagree that big adtech's reliance on dopamine-driven addictive behavior is real evil, but regulations that at least wall kids off from that makes sense and there's all kinds of research to suggest as much, in contrast to a personal essay about a video online.
