It's good to look at addiction this way, but it's a bit oversimplified: Mainly, the role of genetics shouldn't have been omitted. Some people get addicted even after some short time in a hospital - they may have "very good lives" and still cannot get rid of the addiction, because they're genetically predisposed this way. The problem with this video / book is that it considers giving morphium to patients normal and OK, while it's been already discovered that it's too dangerous, because a non-negligible % of them turns into addicts and struggles terribly for a long time.
But anyway. thanks for the post. The video brings very important ideas.
