When I was studying Mandarin Chinese at a school in Shanghai, borrowed a book on Shanghainese. The reason why everyone in shanghai aren’t writing “everything different” is because they are not writing in Shanghainese. They are writing in Mandarin.
I disagree on your assessment of Japanese. I would argue that Japanese is the most difficult written language in common usage / not artificial.
Moreover, one of the greatest literary achievements of Japan, “The Pillow Book” is written entirely in hiragana. Today you have so much text that leans into the resolve of ambiguity that kanji lends that you’d lose a lot of writings were everyone to unlearn kanji, but I disagree that it’s an aid, and had Japan developed its own writing system, it would have felt a lot more like hiragana than kanji.
