It sounds comical that suddenly something becomes valuable because you hang it in a gold frame, make minor modifications to it and ascribe it some symbolism. But that is exactly how contemporary artworks are done.
If you go to exhibits and auctions, it is not uncommon to see highly valued work that requires little sophistication to produce. The days you would woo the art world by technical mastery alone are (mostly) over. This story fits in the greater trend and there might be a bit of a culture clash.
I'm inclined to think that the general public underestimate contemporary art and the art world overestimate its superiority over the more conventional works. Whether it is for better or worse, I will leave you judge of that.
