Ok, so... are you buying the wine or are you buying the place it came from?
Like, there's nothing magical about the towns of Champagne or Cognac that makes the wine they produce different. It's all in the process and expertise used to produce the wine. If you brought the brewers and growers to another part of the world with the same soil and climate, and told them to make the same thing they make in Champagne and Cognac, they would produce identical[0] wine.
And the current regime of "terroir makes the trademark" leads to suitably absurd results. Like, if a Champagne producer wants to expand their operations, they can't, because there's only 75,000 acres of land you can legally make Champagne on. France has been trying to add new villages to Champagne's terroir since 2008 and the process still isn't done, even though the villages being added are literally just in between other Champagne villages. People still clutched their pearls about France diluting the brand purely by just allowing more of it to be made.
Ok, so maybe it's silly, but it shouldn't matter, because Champagne is a luxury product and I'm a [1]smelly American neoliberal that thinks you shouldn't be able to trademark a whole town. Fine. What about a staple food like rice? You see, India saw the EU PDO system and realized they could use it as a weapon to beat Pakistan with. So they're going to the EU and crying bloody murder about how poor Indian rice farmers are being crushed by evil Pakistani rice counterfeits[2]. Defining any sort of terroir here is a political statement not backed up by reality: both countries are either perfectly capable of making basmati rice, or we need to look at micro-climates and other things that would probably exclude a large portion of both countries' rice farms.
>If the Moldovan spirits industry has a superior product, why can’t they call it a relevant name that protects the integrity of their creation?
So, the thing is, often times there isn't really a generic equivalent name. We have "sparkling wine" for Champagne, but that seems to be rare. For example, I've no idea what you'd call non-terroir - but still otherwise well-made - Parmesan or Mozzarella cheese.
