I like this subthread; both of you seem respectful and clear and I'm doing my best to follow the arguments. But I'm having trouble as a result of the choice of icecream/gelato words. I interpreted @robertlagrant to be in the "gelato is icecream" camp (which seems reasonable to me in a "baguettes are bread" sense). But @hiAndrewQuinn, you seem to be in the "gelato is not icecream" camp. I would call this is an arguably correct position similar to "chicken tikka masala is not Indian food," but I doubt most people holding either of these positions would consider these kinds of small differences likely to be the trigger for a business becoming unviable. So perhaps you didn't know what gelato was? In either case, I think you two need to be using the same definitions for your illustrations to make sense. And I really want them to make sense because I want to understand :)
