First, the camera image is not always immediate. If you try to steer your robot by looking at the screen, you're very likely to overshoot the target direction while you try to line things up. Second, it's just a whole lot easier to not have to look at the laptop screen in order to aim your robot.
Basically, a moving spot of light on the actual tower, where the driver is already focusing his or her attention, is much simpler to deal with than a flat and slightly delayed image of the tower on the laptop.
