However, it is also true that there are not only artists who define Art or fine-art as a commodity, and that many of them have the desire to advocate "beauty.

To do so, and to advocate the idea that "art is to create beauty" is to be called "pale-immature" by the art world, which is a popular society.
You're a pale, so you must be an artist, right?
It's a “zero-horizon” marginal art, but there is something called "photographic art" here.
How about Japan, where photography can be called "beautiful"?
