A book is not measured in any of those terms? You really think that the psychological effects, the size and shape of paragraphs and chapters, the ability to create a flow that affects readers impressions, to act on expectations? You really don't know much about writing it you think that text is all that matters. A mrer collection of sentences does not a great book make.
Maybe, maybe not, but I do know bits about human psychology. The point I'm making is that responses to a piece of art are very much individual and personal. They aren't statistically measurable in the sense that the behavioural or cognitive effects of a buildings' structure on the public are.
Nor do they rely necessarily on following a correct structure to be valid, as evidenced by quite a few absurdist and experimental disciplines, some of which do in fact employ entirely free form. Narrative structure tends to follow conventions for the sake of accessibility, much as the 3 minute format makes pop music accessible. More complex non linear and unconventional structures are used for a variety of purposes in terms of (for example) symbolism, exposition or reflecting the chaotic nature of human thought processes.
However there's no reason to presuppose those structures are indispensable, much as jazz or numerous experimental forms dispense with many musical conventions.
Therefore to claim there's some "correct" way to tell or interpret a story, available only to an elite few, is at the very least presumptuous, not to mention inaccurate.
