I think many people have an intuitive sense of what makes a good composition, and therefore what constitutes the 'rules', (without them needing to be acknowledged as or called 'rules' at all). Which doesn't mean discussion with others can't be helpful, and suggestions may inforce or break so-called 'rules'. Rules are useful either for schools of artistic thought and practice that want to keep to certain conventions, or they are for people who actually struggle a bit to get a successful composition visually. But they do need to be considered with care - maybe to come with a user safety warning .
