Your point supports what I have been explaining why I feel that so much of the Hollyweird crowd is so impressionable, or should I say gullible.
They have spent all of their time being someone else that they have totally forgotten who they are. So in desperation, they are gullible enough to latch onto anything the crowd around them tells them they are just to be accepted. It is an overriding deep desire they have to be liked.
I was watching the History of the Eagles yesterday and something struck me about how they went for total abusers of drink and drugs to a total ban on them while they were doing anything Eagles. It hit me when they were talking about how accepting the crowds were when they got back together that I put this one to my sense of logic.
The euphoria they feel while on stage is the thing they were trying to put into their lives off stage and tried everything they could to keep that on stage feeling when not performing. It was only in their retrospect that their love of the music combined with their families was good enough and the performance was just icing on the cake.
I think you are dead on in your personality analysis.
Your point about the Eagles and their ban on drugs is further borne out in the lives of many other stars both in the music and acting world. Aerosmith, Robert Duvall, Gary Oldman, Anthony Hopkins ... the list goes on and on.
Then there are those who don’t get that message and their names are those lamented as passing too early - Joplin, Hendricks, Winehouse and many, many others whose lives end at midpoint because of immersion in ersatz euphoria.
