Good news, social media has been extensively studied and found to be addictive. So we have little need to tread carefully, we already know it’s addictive.

Fortunately it also has minimal to no value to society, so even if we overreacted and banned it completely it’d be fine

Ah OK. Yes I agree, there can be a blurry line between something a person does compulsively/addictively and something that he just enjoys doing. And it's different for different people.
