No one does it in isolation. The goal of having a common formal notation is for everyone to share solution unambiguously with each other. We have mathematical notation, choreographic notation, music notation, electric notation,... because when you've created something, you want to share it as best as possible to others. If not, you could just ship the end result and be done with it.

So no the point of writing music is not to hear it and enjoy it. To do so you just find an instrument and perform. You do not to do anything else. But to have someone else to do it, you can rely on their ear, their sights and their memory to pick things up. Or you just use the common notation to exchange the piece of music.

Yes, they do. There are plenty of solo developers out there. And plenty of solo musicians who write and perform music.
