No, destroying a Logia's body faster than he can reform won't do him any harm, it will only stop him from attacking.

Zoro didn't hurt physically Monet but mentally. His attack didn't wound her body but during just a second, when he cut her in half, Monet genuilely though that she was dead and it broke her spirits.
