The difference is that Lemmy is an answer to Reddit, not Discord. If a Reddit user wants to see if there’s a community for woodworking, he can search for “woodworking” and find it.
If a Lemmy user searches “woodworking” and the biggest woodworking community isn’t on your instance, you have to leave Lemmy and use an external service to search more instances and even then you might not find what you’re looking for.

I don't agree with your conjecture about the user not understanding how Lemmy works. My understanding is that he does not think it's a good system.
