That’s still just a property of the physical product. That’s just half the story. The important thing is keeping the production in the original region. So I want it to have the competitive advantage of the name. As a consumer I want my money to support the producers in the original location, which is easier if I know that the name means it’s produced there.

Note that zero of these arguments have anything to do with quality or whether I could even distinguish the product from one made elsewhere. That’s secondary.
