Personally I find "labels" important -- not for the outside world, but for myself. They convey other people's insights into their situation and allow me to compare mine to theirs and see if there's resonance there. If there's resonance, then they might be a model to me. If there's not, then I know they're on a different path. Like I said, I spend most of my time figuring out what I'm not -- I keep hoping it will lead me to find what I am.
The other thing about labels is my old saw that you can't have a discussion about ducks unless there's a word for ducks. It's true that ducks are things and you could use "things" in place of the word "ducks" but words that are more specific allow more effortless communication. I often see people here saying that they are OK with being male but don't believe it describes them completely/correctly. Demiboy may be the concept they're struggling with in a single, handy word.
I don't expect it to catch on, but it's interesting.
