I'm pretty sure some of this argument stems from the common problem of:
"How many apples do you have?"
"I don't have any apples."
The above statement isn't an answer to the question. For the question to actually be answered you must state that you have 0 or no apples. Both statements, however, describe the same state, regardless of whether or not the person in question has just eaten his last apple. Having nothing is therefore equivalent to having 0 of something.
0 is indeed a value but it is the value of nothingness and therefore is neither positive nor negative as it is neither an apple nor a void where an apple should be. And from this my idea of what a void is begins to fall apart
