No need to see everything in black and white. There are a lot of shades of gray. You're correct that humans work in groups, doing things alone is inefficient, harder and possibly dangerous.

But being alone and learning to deal with your own feelings and thoughts is a good way to mature and know oneself better. Also, there are a lot people that need time alone to recharge and regain energy that they spend socialising and interacting with people.

So there are benefits of being alone.

BTW: haven't read the book and do now know what exactly it is about.
