True but I doubt it applies to lasers. Lasers don't work on slime or liquid-based organisms in anime. Electricity is super effective as seen in the Festival Arc, which means Juvia's body isn't made out of pure water and as long as it is impure she can be killed. But as we know, she can indeed be injured by most attacks, so I doubt Mashima is putting that much effort into Juvia's water body. In the finale of the GMG we just see her battered and bruised with nothing specific to suggest how she got the injuries. The water body seems more and more like a gag.
