Why is it any less natural than a vinyl album in the first place? For example the concept of A and B sides is simply because there are two sides to a vinyl record. I don't know much about the evolution of albums but I assume it's just arbitrary and a result of the underlying technology plus consumer expectations.

That's fair. It was mainly the constraints of the medium that lead to ideas such as rock operas. Now that the constraints of physical storage are lifted we've seen new concepts.
