That’s why there’s always the argument that the country should not be called “America”. English speaking countries split North and South America as separate continents, so America the country does not get confused with America the continent. In Spanish (might be regional), it’s all one continent, so someone saying that they are from “America” doesnt narrow it down to a country.

I think it’s fine to just have different conventions in different languages. If you want country names to be 100% unambiguous in all languages, you basically have to change the name of half of the countries out there. E.g., “Deutschland” could refer to all germanic-speaking countries, but everyone recognizes that it just means Germany.
