Cheese is actually a tricky example. Cheeses produced outside of their origin geo tend to have somewhat different microbiomes and, therefore, somewhat different tastes and other characteristics. See, for example, this episode of Gastropod: https://gastropod.com/say-cheese-2/

I'm by no means an extremist on the topic. I think it would be pretty silly at this point to say that only Cheddar from Cheddar, England could be labeled as such. But origin naming rules aren't silly either.
