If parents are okay with their kids using social media, I'm not sure that I should have the right to tell them otherwise.
How would a ban even work though, without ultimately depending on parent intervention? Companies could throw up a "are you over 18?" banner, but those don't work. They could go full KYC and require users to provide government issued IDs, but that feels like a drastic step away from privacy and data security and could still be dodged when a kid grabs a picture of their parent's ID.
I'm not saying there's a clear path forward. And to be honest, I'm not even really advocating for a government ban. The cynic in me says, "Hey if I raise my kid better, it's just an opportunity for them to be better prepared than someone else's kid." (i.e. Less competition)
But the optimist in me says once a kid grows up, there's a ton of "past wrongs" that they can choose to right, given they have the proper self awareness.
There's also a chance I'm just flat-out wrong, but... I'm betting my child's future that I'm not.
If some parents are okay with their kids smoking and drinking and peddling drugs, are you still not sure that you (or rather, "the state") should have the right to tell them otherwise?
Legislation would benefit children who were born to parents who do not understand the risks.
