There is worth in the spiritual sense in that all living things are worthy and all of man are created as equals.

There is worth in a sociological sense in that a disabled person may be a positive contributor to the society in one way, but because of their disability cannot be in another. Similarly a niche artist is a positive contributor in their niche, where an unpopular artist indicates they may be considered less of a contributor than others.

In the sociological sense I would argue yes it is possible to compare “worth”.
