I will argue with you!
Real talk tho, respectfully, I point to ESO. It is an Elder Scrolls game, so you can't for a second tell me it's not based in a very heavily story-driven IP; it is designed to appeal to both MMO fans and TES single-player fans, so it does not flinch away from giving you heavy narrative to play with; and the entire basis for your character's beginning and continued existence is framed around the larger story. Every chapter begins with an intro quest to set up the plot for the expansion. Choices you make define the game world (read: will instance you away from people who made other decisions), and every raid is a specific fight in a specific climax for that chapter's plot.
Never once do they make us do the story quests. Never once have any of us complained about doing the story quests anyway. In fact, we love them. Why? Because the ones who do them are the ones who want to do them (or achievement hunters, which is basically the same thing lol).
TL;DR: you can be hella story-focused and still not strongarm your player base into running your content while also still achieving a large completion ratio for that content. It doesn't hurt that their quests are all voice acted by some serious talent, but that's a subjective opinion probably.
