Because a calzone is not simply folded-over pizza.
I may describe it a like a small round pizza folded over on itself then baked - for someone with no idea, but they are very different things
Calzone has no sauce in it, for one thing.
Because they’re baked, they have a very different texture and flavor profile than pizza.
This is like saying an omelette and scrambled eggs are the same thing. They aren’t.

Sauce is on the side, marinara.
