If you like looking at 'Starry Night' or water lilies or whatever, then why does it matter if it's an original? If the artist is still alive, and you want to support them, I get it. But if you want some famous dead guy's work, that's just a way for rich people to show off. It's the upper-class version of driving a giant Hummer.
I felt like I couldn't meet a single rich person. Regardless of where I live, they don't want to talk to me. I threw a barbecue and invited the whole neighborhood, and nobody showed up.
