Yes, graffiti can be excellent art, when someone has permission to paint on whatever surface. Otherwise it's vandalism and disrespectful of the owner of that property.
Back in the 90's I worked at a video game studio and there was this guy who spray painted graffiti on his own backyard wall near my workplace. It was so good, we gave him a job.
