In some way I have found copying other people's work a bit interesting. Remember in school when you tried to paint or do what your friend was doing only to claim you did it yourself?
One of the unique traits about humans are we are copying everything around us. Without it we would never have gotten to where we are today and it's actually one of the traits that makes us largely different from some monkey species.
Not saying taking others work and claim it to be your own is right, but it's in our nature. It's only a problem because set ourself certain norms that we shouldn't do it. but it is a fundamental human trait that has made the world grow and it's never really gonna stop.
Just a different perspective:)
