Non-NULL is really only a particular case of having a type with a constrained set of values. It isn't all that special.
If you allow a crude analogy: Constraining a nullable pointer to be not null is like sending an invitation to your birthday party to all your friends and also Chuck, including a notice that Chuck cannot come. You are defending this practise based on the observation that some birthday parties have a required dress code.
