I consider myself a huge music collector/enthusiast that maintains a carefully organized collection and the file system is way too limited to handle anything but the most simple music organization and browsing tasks. I’d go as far as far as suggesting that relying on the file system is a rather casual way of handling a music collection.
iTunes brought library management and meta data editing to the masses, which is a good thing. While Roon is my main player/management software I still use iTunes to sync to iOS devices. Of course I won’t let iTunes move any files - there’s an option that tells iTunes not to move anything. So you could actually have it both ways: Use your preferred file structure and benefit from proper library management software.
