Andy Warhol had a Factory of people working for him too. Damien Hirst does now as well. It's not uncommon at all for artists to do residencies with big name artists. Have you ever had a gallery show? Let alone a whole museum at your disposal to do something with creatively - it's a ton of work, even for a group of people.

I'm agreeing with you though, this is art. Sometimes, so is my mom's cooking.
