I think my perspective of the user's goal is actually the same (or close enough to the same) as David's, just stated differently. The user wants the most local copy or, failing that, a way to order it from another source. However, I have plenty of examples of faculty and occasional grad students who are willing to make the trek to a nearby library -- even out of town libraries -- rather than do ILL. This doesn't encompass every use case or even a typical use case (are there typical cases?), but it does no harm to have information even if you can't always act on it. The problem with OpenURL tied to a particular institution is a) the person may not have (or know they have) an affiliation to a given institution, b) may be coming from outside their institution's IP range so that even the OCLC Registry redirect trick will fail to get them to a (let alone the "correct") link resolver, c) there may not be any recourse to find an item if the institution does not own it (MPOW does not provide a link to WorldCat).
