We don't even have to speculate, isn't it already the case for <13yo? Or is just Europe? Anyway - yeah, of course they're still on it. Expect less compliance and harder enforcement the older they are, not more/easier.
The only protection in the Us is technically “collection of personal information” via COPPA[0] which you can argue would kneecap social media. Any parent can provide consent for their child, however. Children themselves can also just click the button that says they are over 13 if it gets them what they want.
