The only thing I "learned" from this Salvatore Garau in this text is that this sort of art is but one expensive form of institutionalization of commercial bullshit.
You might enjoy the film "The Square": https://www.imdb.com/title/tt4995790/. Hilarious send-up of this BS. Try to avoid reading any spoilers, it'll be much better that way.
Sometimes interesting. But I recall an ugly mess on the wall of Tate Modern with a card below which included "...then we shot it with a real gun..." . Britain has very strict gun laws so most people have never used one. Use of the word 'real' left me with the impression the artist had gotten over excited at something which is commonplace in other countries, and confused that with creative endeavor.
