Good.
I'm far from a social media fanatic, but make no mistake that the primary purpose of legislation like this is to increase the degree of control that parents can exert over their children - not to improve the wellbeing of young people.
For teenagers from marginalised groups living in oppressive households: social media can become an outlet for self-expression amongst trusted peers which might otherwise put them at risk of retaliation from abusive parents, or a venue for them to discover like-minded people and organisations who might be able to help them cope or increase their available options by offering sanctuary should they ever need it.
It also can't be overstated that social media is one of the main venues for political expression nowadays, particularly beyond the orthodoxy. There remain issues with misinformation and the far-right, but nonetheless the breadth of opinions can help people to develop a degree of political consciousness which they might not otherwise. Consider how infrequently sympathetic portrayals of protests, strikes, and unionisation drives make the mainstream media in comparison to social media.
It's unsurprising that the politicians most aggressively pursuing legislation like this are also the ones who are trying to prevent, for example, queer people and especially queer youth from being able to express themselves without fear of reprisal - and who are actively trying to prevent access to information and depictions which might contradict their political ideology through mechanisms like internet censorship and book bannings.
