Generally, I agree with David.  Use rarely results in better preservation.  The example given of a Stradivarius violin being played does not enhance its preservation or survival - tensioning the strings can cause damage and does not prevent other deterioration, and in fact promotes it.  Does enhanced wear off-set the risk of parts "freezing"?  It depends upon one's perspective.  Frozen parts are often recoverable in the future, with most of their features intact.  Worn parts are often not recoverable and information can be lost.  This is most severe when a "restorer" replaces worn parts in an effort to keep an object functional, rather than historically intact.

If stable, reversible techniques and materials are used to keep an object minimally functional to prevent freeze-up, but yet safely preserve the original components, both needs can be met.  However, keeping string tension on a piano definitely leads to distortion and other deterioration, so this level of functionality must be avoided.  The specific object needs must be carefully evaluated to determine the best course of preservation.  It is best to err in the direction of preservation of original/historic components, rather than functionality.

There are some classes of objects—such as musical instruments and machinery—that a museum might want to maintain in working condition, even if they are in the permanent collection. In order to do this, they have to be (carefully) “used” and maintained from time to time. How much is a Stradivarius worth if it’s deteriorated to the point that it’s not playable?
