> Japanese is only spoken language like others basically only for small children and idiots. Literate, grown-up Japanese is a written language first.
I seriously doubt that. Literacy levels rose in Japan during the Meiji era and that produced pressure towards simplification of the writing system. Sure, Japan didn't go all the way to a pure kana system or to a latin-derived script, but the reasons are political and cultural (and there is nothing wrong with that) rather than linguistic.
In any cases, you didn't disprove my point, which is that the need for kanji is self-fulfilling. It feels necessary, precisely because its usage prevents the evolution of the phonetic kana system into something useful.
