In this case you may be right, but region protected products can be quite ridiculous. For example Bourbon:
- Produced in the U.S. and its Territories (Puerto Rico), as well as the District of Columbia
- Made from a grain mixture that is at least 51% corn
- Aged in new, charred oak containers
- Distilled to no more than 160 (U.S.) proof (80% alcohol by volume)
- Entered into the container for aging at no more than 125 proof (62.5% alcohol by volume)
- Bottled (like other whiskeys) at 80 proof or more (40% alcohol by volume)

That’s pretty fucking generic except for the made in USA portion. If I’m not mistaken Champagne has similarly silly restrictions with no significant difference.
