There's a couple things. I just finished my catalog today, so I guess I can talk a bit about the challenges that I encountered.I see. That's an interesting take. May I ask what is the massive headache that comes with catalog trades?
Whenever you're several hundred items away from finishing your catalog, you're probably going to have to make a bunch of large scale trades. These trades take tons of time, usually because you either have to shovel through your storage or time-travel several days over to get orders ready. (More generally, people massively underestimate the time it takes to complete catalog trades that are larger than 1-2 items, unless they've done it themselves.) There's a lot of smaller things that go into it (keeping an updated list, juggling multiple trades, not messing up color variations, etc.), but overall it's pretty exhausting. Even after going to five different cataloging services on this site, I was still missing more than a hundred items. Bulk cataloging services tend to have quite a bit of overlap in what they offer, which works against you.
As you start getting closer to completing your catalog, locating items becomes a lot harder. It's not difficult to find someone who has the surfboards, or the diner set in one color completely cataloged. If you're, say, looking for the throwback wall clock in purple, that's a completely different beast. You start having to make smaller trades, but you have to make more of them to make the same progress. I was lucky enough to find someone who was ~70 items from finishing their catalog, and letting them get most of the last 15 items that I needed.
<tl;dr> finishing your catalog is very painful and time-intensive
