If we remember an idealism, it would certainly be complete. Besides visiting galleries and studios, it would be meaningful if there were a curator who could provide economic value so that the artist's livelihood could also be supported. They could enjoy the work and gain satisfaction, but also receive financial support for a work that was free from commission. Because even if someone funded an artist's work, their sincerity would be questionable, or at least the artist would be bound by the amount given and lose their idealism in their work.
You're right about why there must be terms like and dislike. However, that's all reality. If everyone understood that art was for art's sake, there would be no such thing as like or dislike.
However, in reality, we cannot deny that a fan of realism will certainly feel out of place when visiting an exhibition of surrealist or abstract works.
And it turns out we come to know our own faces. Like @almaguer, painting certainly wants to reveal one side of one's face or one's feelings.
Or at least it can make us reflect so that when we see a face that is not a carnival mask, we will be reminded of a nuance that we have experienced or are currently experiencing.
