I've always found this to be an interesting debate, if you want to call it that. Art frequently gets the reputation that it isn't work. I feel like the associations it gets is "Oh, these are the people who think they'll be a super star. Well, reality will hit them and they'll fall flat on their face and wish they went to school as an engineer or some REAL job"
I love art. I've always found drawing to be a hobby. I tried my hand at creative writing. I never really wanted to make a career out of it, so I always likened it to a hobby. I wonder how much of that was influenced by the "Art isn't real work" logic nowadays.
For me, as I grew up and realized more things about the world I realized that art can be just as much a job as anything else can be, it just has a horrible reputation. I have taken a couple of creative writing courses and those were really difficult at times. It seems like a simple concept: sit down and write whatever you want. Well, I feel like a lot of students hate the "write whatever you want" even when it comes to research papers. We want guidelines and requirements. Creative writing CAN have requirements, but it's so free it's intimidating. After creative writing was over I realized I just don't have what it takes to be a creative writer. It would take too much mental effort for me to sit down and write the intricate stories, complicated plots and so on that you would need to be good at in order to make a name for yourself (unless you somehow got lucky and wrote a piece of garbage like Twilight and still managed to make millions).
Basically, I think that writing, drawing, sculpting, whatever form of art it may be can be just as challenging and just as intensive as anything else. It may not be something that you see physically, but mentally it's definitely there.
... Although at the same time, I still definitely have my opinions on what is art and what is not. (The Walker or Weisman or the stereotypical corporate art sculptures you see, for example, I do not consider art)... and I guess perhaps that's where the discrepancy lies. What IS art in the first place?
