even if you close yourself in room and never ever get out, and constantly make music, it would be weird and all but still be "morally" ok.
"morally" because really, it has no place here. You don't necesarily have an obligation to help society or whatsoever. If that concept is not in your mind, it is perfectly fine.
After all morality is a very subjective concept and depends on each person's character, but it is an intrinsic thing, it is based on your perception of reality. You follow what you believe in, but not everyone sees it the same way. We have laws for that to determine what's right and wrong for the State.
But morally? that's up to do, I don't mind.
I personally think there's no morallity involved at all in that question of yours and find it pretty stupid.
