All of your points show an absolute ignorance of jazz. Jazz has been around for over 100 years and I can find artists in every decade that would disprove all of your points. From Louis Armstrong and Duke Ellington to contemporary artists like Ezra Collective and Moses Boyd there are plenty of examples, of course there are also extreme examples that do meet your criteria but that is not all there is to jazz just liked Norwegian Black Metal isn't all there is to rock.
