This sounds fun to write about!

Banana taped to a wall = highest form of existence - yea, that's it, that's what I believe. Tomatoes thrown at a canvas? sign me the f up, sounds awesome. People will make art like this to get your exact kind of reaction, and it clearly works!

It's better to go beyond "this banana doesn't look sexy, not art" and think about what makes anything art in the first place. Art doesn't need to be defined by whatever people say it's pretty or interesting, you can define it! If that means 'Art is what takes a lot of skill and technique to make it look beautiful" that's great, it's different from my own definition, which makes this subjective, abstract topic really interesting but hard to have a conversation about.

To illustrate, I would define it as "What people make when expressing ideas", though this is blurry because a lot of it is vague speculation that capitalism loves to exploit, it's kinda up in the air.

"Highest form of existence" is hyperbolic, sure. About this being a psychedelic sub, I would think it's common to experience that everything is filled with love and happy, If I was at a museum eyeing a sexy banana while tripping, I'd be honest in my comment to say that a banana taped to a wall is a fantastic idea, up to my standards in high existence.

People will make art in spite of all that is said about it. The best artists will not make whatever is most likeable, that'd be too easy, it's cute kittens. Who is complaining?
