That's because real art, like anything (engineering, piano, sports) takes years and years of hard work to perfect the skill which gives the ability to translate your ideas into something beautiful and self-explanatory (when you don't need to be expert to "understand the meaning" as it is with masters like Michelangelo).
A great example is when Henry Moore saw Michelangelo and started to cry and confessed the only reason he makes such statues is because he knows "he will never be able to create anything as beautiful as that"
Perhaps he would if instead he worked on things that are hard.
It's hilarious how modern art lives on creating documentaries, popularizing an "artist" then selling art for investment while fooling people by using shaming tactics like "you just don't understand art" or "that was not the point artist was trying to make"
If the artist has to explain her work in words he should have chosen literature as a form of expression for clearly she failed using her current means to do so.
