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.

To add to the confusion, sometimes I do stupid things just once. Even so, those things should be banned, for harming me.

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

Good news, the thing you like had been found to be addictive. Please relinquish your freedom, this is for your own good.

If by relinquish freedom we mean, respect other people and limit your vice to controlled settings where harm is minimized.. yes.

You can still smoke, drink, get high, and gamble. We ask that you limit these to places that minimize the damage you do to other people.
