Miyazaki said that he does not design his games to be specifically difficult but he wants the player to experience the joy of overcoming a obstacle by learning from mistakes and finding solutions.

And easy mode in that case would definitely destroy the intended way of experiencing the game, because struggling is the concept of this game.

If you’re talking about accessibility settings (eg colourblind display settings, subtitles or alternate button inputs), then fine, I agree they should be as all-inclusive as possible. But you’re trying to railroad or force the creator into changing their artistic vision for the end product. They want it hard to beat. Its entirely optional to play it, if easy to beat games are more your speed, Kirby or whatever already exists.

I don’t turn up where you work, knock the dicks out of your mouth and demand you do it differently.

The entire idea is a dark unforgiving world and having difficult enemies is a part of that theme. Beyond that the encounters are carefully designed to challenge you and be easy enough to overcome as you grow in skill. The combat is everything in this game and was designed for a very specific experience. Combat and theme are what people love about these games. Changing the difficult would alter that aspect and thus the core experience of the game
