Why go to art college at all?

I was posed a question from one of the people in the film department. One of the obviously more experienced and older students. He asked why in the world would I need a Bachelors in Fine Arts when all I need to do is submit my work to some gallery and have them hang it. I never need like arguing with people that didn't know what they were talking about. I'm not saying that the guy is stupid. I'm just saying he's ignorant. I was tempted to ask him the same question only switching Fine Arts with film.

The bottom line is this: There is a lot more that goes into any art form than simply putting lines on a piece of paper or shooting something onto film.
