But music cannot be shared as an idea. It can be demonstrated/performed.
If my idea has costs associated in order to be able to share it, and I don't receive any value in return then I stop sharing my idea because I can't afford it.
Does fewer musical ideas being shared also not hold humanity back? Should I be forced to labour without compensation in order to perform an idea that should flow freely?

Rhetorical but feel to if you have answers. I certainly don't.
