You make good points, I can see how an organisation can work with the tasks I described subdivided into equal roles. And it might be more democratic that way. To me it doesn’t discredit the meaning of the word leader though. Words often don’t have a single definition that works for everyone, and I agree that this word has lost its meaning in general. But in the associations I mentioned the word does have a clear meaning as I described. So in some contexts I do think it makes sense to use it.
