A lot of people agree with you. He had an exhibit in central park a while ago and most people I knew thought it was a pure waste of time and resources. Only a few who were in art school at the time cared about it. They even volunteered to help build it.

Since then, I haven't heard another mention of christo, the central park exhibit or anything related to that by anyone. So makes me wonder what the point of it was. But if it made some happy then so be it.
