I would largely agree with that.
However, when playing in a band together for an extended period, I doubt I'm alone in finding something special often happens, where you develop a bond that's not exactly friendship, necessarily (although it can be), but is...something. Like being on a sports team for an extended period, perhaps. And I'm not sure I've ever found myself with quite the same kind of bond developing with people I've worked with, even ones with whom I've worked for a long time, and even though some co-workers have ended up becoming better friends than any musician with whom I've ever played.
There just is--or at least can be--something that happens when you make music together.
