I think ghosts are eminently collectable because of their uniqueness. Most ghosts are wet sheet transfers. They are very rare results of random occurrences in the factory and offer a collector something very different from a run of the mill card that nicely complements a regular set. It also allows you to continue to pursue a favorite set even if you complete the base set. For example, I readily completed my 1948 Leaf boxing set but can still collect it by going after blank backs, ghosts, wrong backs, missing ink cards, etc.
Ditto for back variations, esp. T cards. Collecting a master set or a back variations set is a whole new level of complexity and challenge. I am master-setting some of the T boxing sets and having a great time doing it. Plus, there is the treasure-trove aspect to it, as anyone who's located a T206 Piedmont 460 factory 42 in a commons bin knows.
