Sure, for a dentist or doctor's visit, it's totally reasonable. But if you were asked for your ID every time you bought a burger at McDonalds, it would be considered suspect and a potential privacy invasion by most. The same is the case with social media.

There is no governing body that determines who is and who is not "authorized" to request ID in the United States.
