If your ethics are such that you believe the state should be able to view data on someone in order to help prosecution of a crime then you could support the retention of data on all users in order to avoid deletions made to hide criminal activity.
Such an ethic creates a moral reasoning to not comply with an individual's wishes in the immediate deletion of data.
(FWIW I'm not defending this position nor suggesting it's the case here, just you said there's no moral reason that can support it, which seems wrong; different ethical systems can provide different reasoned moral outcomes.)
There might be something to that, in the sense that I could very well see someone in a meeting ask 'well, but what do we do when another user is tagged in a photo' followed by discussion rationalising why that person shouldn't lose out because someone wants to delete data, and someone coming up with the 'solution' of effectively reference counting the data and figuring out when to actually purge the underlying file later (i.e. never)

Why, to help people connect better of course...
