Now, I tend to think those internet pedants are boring and obnoxious, but the entire reason we have to have a discussion about the "myth of the national dish" is because of people like them.
Once you decide that these things don't matter and food should just be enjoyed without caring about "authenticity" and that every tradition is only traditional in a certain context and time period, the whole idea of fighting about it kind of gets silly.

Back in the day people had no proper phyisical dishes (read: recipients) and they just ate food on top of bread slices.
What makes it pizza specifically at that point?
* White clam pizza
* Amici's Milano or Trentino
* State of Mind's Peas on Peas on Peas (when it's in season)
Why would the lack of tomato sauce make it not a pizza?
(You didn't specifically mention tomato sauce, but GP did and it sounds like you are in agreement? Please forgive me if I misunderstood.)
Is crostini a pizza? Is bruschetta? Is sabich? Is lahmacun? Arepas? Is an open face bagel with cream cheese?
Of course if the pizza dough is wrapped around the toppings/fillings and pinched around the edge in a half moon shape, now it is a calzone, not a pizza.
Or is it an empanada? ;-)
And thank you for that list! I have never had sabich or lahmacun, so you have given me some new things to try.
