You want your images to tell a story. Like any story, there needs to be a string that connects each part of your collection in a coherent manner. Without that string, you would end up with stories that make zero sense, with no real plot, structure, or sensible dialogue (like most blockbusters of today).
Composing turns your random bunch of beautiful photographs into a whole, a narrative, a single cohesive image. Only a proper composition can arrange and align your images in a way that capitalizes on their function and purpose.
