You can only quit if you want to quit. If you want to quit, it is disorienting, but not all that difficult. The wanting is the hard part.
Breaking an addiction is an inherently violent process (you must destroy part or all of "yourself"). People tend to shy away from violence.
That's an interesting way to think about it, I always saw it as distancing yourself from a dependency. It's much easier if you replace bad habits with constructive ones
It's not always necessary to quit entirely either, some bad habits aren't that bad if done in moderation
