Why do Star Trek and Star Wars fans think that all media must tie into a single, consistent continuity?
All fans don't think that way. I think the reason a lot of them do is that they haven't been given an explicit alternative. All the screen incarnations of Star Trek
have been presented as part of the same history, up until 2009 (and even that's presented as an alternate timeline branching off from the original continuity). And the books and comics are all presented as consistent with the screen canon even when they're not consistent with each other. So it's not like Batman or Spider-Man where they've seen multiple screen and print incarnations explicitly set in distinct continuities. There's an expectation that there's a single core continuity.
As for Star Wars
, there really hasn't been that much screen content up until recently, and again, most of the tie-ins have purported to be in the same reality as the screen content rather than being an alternate version of it. And you have the added factor there of Lucasfilm Licensing actively pushing the tie-ins to be consistent with each other and telling the fans they were "canonical" in some way, promoting that perception quite strongly. The only alternative takes SW fans have seen are parodies like Lego Star Wars
and the upcoming Detours
show from the Robot Chicken
