How would nature be best described as a horrible mess of impossible equations? They would be best described as elegant and beautiful no?
I think your point is more that we might be able to initially describe complex phenomena as messy, horrible complex equations, that doesn’t mean we shouldn’t work to simplify them and make them more understandable to us.
Look up diagrams for cell signaling cascades sometime. It's emblematic.
In some ways it's like a smalltalk system haha. I think you can find some elegance there. The system is overall complex, but with simple primitives.
