I think your quote is quite apropos in this case.
Art is simply creation; anything created with an intent to capture a feeling, or a moment, or perform a feat, or any other "stamp" on existence is "art". That said, art that is typically considered "good" is aesthetic, evokes emotion, and makes a statement. There are, of course, many ideas on what makes art "good", but artistic creations are the ultimate form of "if you don't like it, don't view it."
Lastly, you can get into realms where things are offensive, dangerous, or downright obscene, and projects like this are often started for that sole reaction in the overall population. To me, that isn't art, though to others, it just may be. It'll never be an easy thing to determine.
I agree with you that some things simply don't take much talent or artistic creativity, but narrowing the definition of the word "art" would be like changing the word "life" or "up". Art is a very, very broad term for a reason.
