These days, there are so many ways to illustrate function that continual – or even occassional – use is hardly necessary. While absolutely nothing duplicates the original, there are many ways of recording and playing back function – up to and including 3D scanning and holographic projection. Basically money and evolving tech are your limits. You could even model or 3D print a replica.
Of course, some objects like ritual pieces (or some would say musical instruments) are thought to require use to remain “living,” and that’s a philosophical discussion about the very nature of the piece.
