Interesting to compare this thread with the banning gas one in New York. In general once you accept the government making decisions for you “for your best interest”, don’t be shocked once they start doing things you disagree with.
This is why I generally do not support any bans dictated by the government.
In this case it’s difficult to find a reasonable solution that’s not draconian. You could tell parents to use screen limiting tools but those are unlikely to be used by the parents whose children need it the most.
Perhaps making social media require a $1/year fee with it being returned to you after 6 months would stop the vast majority of children.
