Your points are all worth discussing, but I'd like to focus on one subject at a time. Looking at it, thinking about it, and possibly discarding it as trivial. Toward that end, I will write a post on my thoughts about "structuralism" in experimental film. The term itself, some common beliefs about which films are structural, and some examples of films usually considered structural. Since I'm rather slow-witted, I need to spend some time reading and viewing before expressing my opinion.  Next day or two, I promise.
