I believe "art" is up for interpretation. It is incorrect to say that a photographer is based on luck whereas an artist has to practice. In both cases, luck, instinct, and practice are all essential to an artwork. There are many traditional artists out there that thought they didn't think their idea to draw was extraordinary, but drew it anyway, and it ended up being a success. Couldn't that be considered luck as well? There are some photographers (mostly experimental or amateur photographers) that get lucky, but professional ones do everything on purpose.
To you, traditional art may be the best. Indeed, a lot of effort goes into traditional art; however, you must understand that traditional art is not the only "art." Different mediums of art also require effort, hard work, dedication, and practice. If you look at most photographers, there beginning pictures are not great, but as they develop and grow, just as a traditional artist, they begin to have techniques that make their work more pleasing to the eye. A lot of work goes into the set up of a picture, the shooting of the picture, and post-processing. It goes the same for painting, sculpting, and photo-manipulations, which I have also featured.
I think every artist should explore and experience other mediums of art because that is how one grows as a person and as an artist. To appreciate all art, whether you like it or not, and perhaps dabble in various forms is how one can develop respect for other artists' time and effort.
Basically, what I'm trying to say, is that it's difficult for someone to understand another form of art if they have not tried that medium. I suggest you possibly try taking a few artistic photos and see how they come out and keep trying to develop your skills. I see you are mainly a traditional artist, but if you ever need a small break or fresh air, a walk around the block with a camera may help
