What do you mean by "doesn't really exist" or "fiction" though? We use words to describe things and there is always some abstraction involved (when you say "this is a rock", by rock you mean a complex combination of other substances that I do not describe, but have these general characteristics). When talking about cultures, cultures are represented by the people and their actions and both the people and the actions do very much "exist". Describing it "exactly" seems something impossible (same way you don't include in the definition of the word rock how many molecules it must have). So if your point is "language is fuzzy", sure. But saying "culture is a lie" seems just beyond reasonable fuzziness. The definition of culture implies a lot of summarization which in my opinion excludes an exact definition.
