I would say that contemporary equivalent is data hoarding. There are people who have archives of various media, whether (audio)books, films, music, video games or programs in sizes of tens of TB or more. Of course they will never be able to consume the content, but what if they ever wanted/needed some small part of it? And it's not like it would be useful backup in case of SHTF/TEOTWAWKI scenario either, because the popular storage methods aren't very durable.
