As a writer, I can assure you that, depending on the circumstances, creating new words can be a necessary part of the story telling. For example, in sci-fi, a writer will create a society and a new language for that society. I do that in my stories, I invent languages and, consequently, will invent words for items that have English words for them. However, once it's established that there is a different language being translated, I will return to the correct English words.
