If sex isn't biological and immutable, why is she acting like archeologists can get the sex wrong? Her premise admits that the person had an objective sex; just that long into the future, there is the (slim) potential for an archeologist to incorrectly surmise what that objective sex was.

To my understanding it's virtually impossible for archeologists to determine the exact age a person died from their skeleton alone. This doesn't mean the person wasn't that age. And yes, archeologists probably would use context clues to help pinpoint the person's age, even though they could potentially be misleading.
