Normal modern people are the opposite; everything on cloud no data on hand, except maybe photos and videos captured on phones.

I just do the most basic lazy cataloging like music, shows, games etc. Some people like to do the extended cataloging, it's a hobby for them, so I say if it's fun for them then why not? It's not a waste of time then. If not then yeah, you don't have to force yourself just for sake of clarity/ocd.
