This week, Surgeon General Vivek Murthy issued a long-overdue message warning Americans what they already know: Social media is harming kids. But looking through the 19-page advisory, the surgeon general’s solutions appear potentially more dangerous than these pariah platforms themselves. He is pushing for a critically misguided policy that many state legislatures and regulators have already enacted, a mistake that threatens to undo what little internet privacy we have left. To protect kids from social media, he argues, platforms and lawmakers must enforce age minimums. This is tantamount to requiring ID to go online.
