I don't deny that reading Japanese written in kana alone is currently more painful than with kanji. However, it seems to me that the current writing system is a local optimum and not a global one. If people started writing Japanese using kana alone, some adjustments would eventually be made to make it more readable, and the end result would in my opinion be superior to the current kana/kanji combination. The same thing happened with the latin alphabet. We don't use it the same way the romans used it 2000 years ago: we introduced minuscule letters, spacing, punctuation, accents... At the end of the day, Japanese is a spoken language like all other languages, and there are no reasons why a purely phonetic system should not work for writing it.
