I'm not disagreeing with you, but in my humble opinion, like anything in life, you have to start somewhere to learn anything. Rules of thumb are just that, rules of thumb, not hard and fast rules, but concepts to start with, then expand on. They give you things to consider as you compose. When I took art class 100 years ago, I remember being taught basic concepts first.
The point is they should never be taught as "Rules", because they are not.
There are many good guidelines on where to start thinking about composition. That is the way it should be taught. A place to start, but not the end all of composition. Instead we get people saying they were "told by a pro in 1956 to do it ...", and they have been doing it that way for all those years. They accidentally got it right at least twice.
