Yes, but why would we frame doing what we want (deliberately composing an image, e.g. with the subject in focus, if that's what we want) as "following rules"? It is a little backwards. I guess the obvious answer is that for many if us amateurs, we're not actually visually aware enough to be fully deliberate in composing, so heuristics are useful to arrive at a picture that pleases even when we're not fully aware of and deliberate with all elements.
I think part of the problem is that we're not use to looking at scenes that are two dimensional as in a photo. Our eyes see the whole panorama in real life and in 3D. SO it takes awhile for our eyes and brains to adjust to how apicture is shown in 2D in a smaller format ratio of let;s say 3:4 or 3:2. When I switched from 4:3 photo taking to 16:9 format to match video format, it only took about twenty minutes to adjust how I was laying out the compositions. Our eyes do adjust to format changes and 2D.
One thing that might help is to try moving around a little so the camera is looking at the same scene from slightly different aspects. Take a picture of each and compare when you get home. Slow down and see if you can determine which scene looks more pleasant to you. Things come into play such as balance.
