Look I am gonna explain this once and for all.
Italy was divided for a long time, with regional dialects and regional cuisine. It became a thing of pride to make dishes with what was available, and those recipes get passed down. So each generation is yelled at by the previous if they alter an established recipe, after all it's already been perfected. Don't mess with tradition.
Italian food is also quite simple, it's that way to really appreciate every ingredient. Italians still fight over regional differences, some cunt might insult your dish because it's only made in some town across the country that they don't know and isn't THEIR italian food. Like alfredo is actually a real dish, but most will say it's not. Rose is also a real dish but many Italians say no cream in pasta. Pizza also has a traditional recipe but I've eaten variants that taste like pizza in NYC even in Napoli, the home of pizza.
So it doesn't matter, every culture is a bit autistic about their food. For most cultures food was everything, everyone cooks and eats food, not everyone created architecture or arts, this is the biggest part of a culture because everyone is involved for generations.
Personal story, my family only makes ragù, and the one time I asked for meatless pasta sauce I was told it wasn't possible and I could just not eat it. Never asked again. I love it now.
