If you went to university at 14, which is what... 4+ years earlier then anyone else usually manages? then you really shouldn't extrapolate your own experience on the population at large.
You'd have skipped multiple years in education, hence you'd be massively more intelligent then the general population that this regulation aims to help, (albeit against their own wishes).
What I say is: it’s not age that determines how harmful (and if) social media is. It’s the content that you expose yourself to. There could be ways to retain the benefits of communication networks for adolescents while keeping them away from harmful content - but most parents are too lazy and it’s much easier to ask the government to ban stuff.
