Keep in mind the concept of "structure vs content."

"Structure" is the framework upon which we build something. An example would be a musical staff.

"Content" is the stuff we put into the structure, e.g., notes and rests.

In this thread the structure is "addiction." The content is food, porn, or whatever.

People must change the structure for any real, lasting changes to occur.

Ridding ourselves of one type of content just leaves a vacuum, and it will soon be filled with another kind of content.

Changing the struture makes the content irrelevant.
