What a horribly sad way to live your life. People are no addiction, they're a necessary (and awesome) part of life. Regardless of your spiritual bent: Athiesm - We evolved from social primates into other social primates. You're adding a lot of psychological stress at a fundamental level when you don't live the way you're bred. Christianity/Judaism - God made us for community. "It is not good for Man to be alone". Bud…
Hardly. Few people choose to live in caves, and a life of doing so would probably be more stressful than normal, despite that it's what we're bred for. And I'm pretty sure going to a bar or a rock concert was never part of the ancestral environment.
If you tried staying in, found it made you feel much more stressed and so switched to going out that would be one thing, but that's not the experience the author describes at all.
