They've been making banana wine from wild yeast presumably for at least a 100 years or longer. It sounds like the regulators in their country are a PITA and won't get out of the way.
There's a million different strains of yeast but they all do the same thing. If you don't add any yeast it will still ferment with the wild yeast.
