Smoking kills massive amounts of consenting adults. Far fewer now that people don't start smoking at 14 mind you. Every family member of mine that smoked started before they were 16.

I brought up smoking to illustrate the point that the existence of people subverting a ban isn't mutually exclusive to the positive outcomes. Not to draw a straight line comparison.

comparing social media to cigarettes just because both can be addictive

Also cigarettes are a physical drug

IMO the ban should be below 12 or 13yo, not 16. I think where we need to draw the line is children who are at risk of long term mental health damage or victimization.
