I think it can depend on who's using it.
Personally, I live in a city with no natural community. I'm married but have no family here and only a couple acquaintances. I tried to quit Instagram a couple years ago but just ended up more isolated than I already am.
I think this type of situation is common for a lot of people. Social media is the glue that ties us to friends in distant places, which is why it's successful.
If you have actual community available to you quitting is much more doable.
