Only cheese made in a specific way with specific milk from grass-fed cows in a specific region of Italy can be labeled as such. Scale? Wikipedia reports: "The average Parmigiano-Reggiano wheel is about 18–24 cm (7–9 in) high, 40–45 cm (16–18 in) in diameter, and weighs 38 kg (84 lb)." And each is sold for over $1000. You are looking at over $66,000 of cheese. I watched someone being served a risotto that was poured into a cheese wheel with a well in the center, stirred around to get the freshest cheese melted onto the rice, and then served immediately. I want to order that dish next year in Bologna.
