The need to reproduce the musical venue is one function of a system. I like to call it the "Disney World" function, because it produces the kind of illusions which trick and delight children of all ages.
Other musical pieces are masterpieces of collage -- multi-tracked. Think of Dark Side of the Moon. It is immersive but it is not "realistic" in that simplistic Disney way. Others are electronic. They, too, lack "realism," but a good system will produce tonalities which are arguably more important than spatial simulations.
I know people for whom the gear is the endgame. I do not just them as being wrong. Let 1000 flowers bloom.
