"addiction" and "just ___" are kind of mutually opposing forces. It can be difficult to understand addiction from the outside, as the solution seems obvious, but the internal world is not straight forward to navigate.
If the only way the poster is going to cure their social media addiction is through government intervention, I would suggest finding alternative means of addressing the issue.
I think even those who came into contact with addiction and substance abuse may fail to realize that social media dependence is a very similar thing.
We can get technical - drugs and booze are psychoactive, while social media is behavioral addiction. Even so, the habit-building loop and the compulsion that stems from it is effectively the same.
So, I don't think it's condescending to say "just quit it". I suspend my Twitter account from time to time when I realize I built a habit loop again, and the "urge" just goes away.
