I also agree that places should in general be able to protect origins in some way.

A bit like the US, Australia has had issues with things like cheese. “Feta” must now be Greek, with local feta-style stuff either called “fetta” or just something like “Greek style cheese”.

But there are lots of cheese styles in Greece, and the Australian cheeses are often very good (not always) exemplars of a feta style cheese.

It’s very hard to see where exactly the line should be drawn.

On the other hand Nürnberger Bratwurst (basically sausage) has a trade union suing anyone within their reach for daring to associate their sausage with the city of Nürnberg if not certified to do so.

There might be a somewhat similar situation going on with Parma ham. What I heard is that the meat simply needs to pass Parma in a truck or train to qualify as coming from there. Probably a partly sarcastic take on their hypocritical approach to quality control.
