Let's set things straight. I assume this building's policy for climbing it is that they don't want anyone to do that, but with a structure like this they are practically begging people to climb it. It looks like a ladder. If you don't want people to climb your building, just don't make it so easy. Give it spikes. Or make it very slick and wet. Those are just some suggestions to avoid any possible lawsuits.
For the picture's sake, I'm glad this specific building is very climbable. You can't get this kind of view of China without someone risking their lives. Maybe that's what art is all about. It's about risking your health to give something back to the world. I'll think about that the next time I'm busting out my paint brush. Maybe I'll risk my life by using lead paint.
