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.
