When you say it's a massacre not to get a pizza that looks exactly like the one you make as an Italian, of course, you also have to think about how they get good ingredients and the availability of ingredients for the pizza.
They may have tried, but it's their version of pizza. It doesn't have to be similar to authentic pizza like in Italy, maybe a little change to adjust to their country or culture.
This is what makes it unique and more memorable, rather than everyone making the same pizza and it's pretty boring.
BTW I will also follow it and prepare to buy some raw materials for my pizza.
look forward to mine, maybe it will not be the same as what you want. but it will be an effort to make my version of pizza.
