[ModusOperandi]

Don't know much of Japanese, but I believe that any culture/country/people with a language that can be expressed verbally to an intended audience without losing its meaning or requiring outside/physical aid to create context can have its written aspects/graphemes altered or changed.

It’s just more trouble than it’s worth after centuries of an established system. With that being said, only the Japanese can come to the conclusion as to whether or not they want to eliminate the Kanji from their written mode of communication. If it's such a huge inconvenience or if it is impractical, I think they would have done away with it a long time ago.
