yes -- but on the same show they highlighted people making ridiculous high quality fresh naples-style pizza in other countries other than italy - japan, denmark, etc.
the cheese is the hardest part of the pizza to replicate outside of italy for sure, you can easily buy high quality imported olive oil, flour, and san marzano tomatos.
yeah the guy from Denmark resorted to making his own mozzarella by rearing his own cows - hence the point about exporting.
Japan have decent local dairy (Hokkaido milk) and their overall attitude to produce is similar to Italy which probably is a big contributor to their food culture
