It popped into my head today why I think this is the right comparison. When you power wash a wall, you reveal the color/texture it had before it was degraded by exposure to the environment. In an analogous way to how walls grow over with ivy, moss, and grime if they aren't maintained, websites tend to fall into disuse and become parking pages. So restoring the original content feels analogous to power washing the grime off a wall and revealing the original bricks. It's subjective though, reasonable people may disagree. If someone did what you proposed and called it reverse graffiti, I wouldn't argue the point.
