I guess I should know better than to express a complex chain of thought on something like this.
Pizza did not appear in a vacuum. Baked flat bread dishes were common in and around the Mediterranean for centuries. Pretty sure the Greeks had a baked flat bread they topped with herbs, garlic and maybe onions. The point is, "pizza" did not just appear one day. What started to morph into today's pizza, was the introduction of tomatoes from the New World. Don't forget, the tomato and Italy only goes back about 400 years. However, in Naples, there are really only two types of pizza considered to be "real" pizza, one of them being the Margherita, which only has three toppings: a small amount of tomato sauce, a little cheese..and wait for it...basil.
The concept of loading a pizza up with toppings would be foreign to the people from Napoli, whereas the use of basil and garlic with a little cheese certainly would not be. Granted, pesto is not tomato sauce, but as baked flat bread dishes and pesto both pre-date the arrival of the tomato in the region...well, I hope I've made my point by now?
