  You're not getting a job or learn to drive at 13 where I live.

  Social media should be for 18+. Kids shouldn't see what adults post, and adults don't want kids sharing their platforms. >
  
  There isn't really a legal mechanism for it, 13 is just the standard bar for when you aren't considered as much of a "kid". It is where school starts being your responsibility, where you start to learn to drive and get a job, etc.
