The point of Isekai is to imagine yourself in the role of the protagonist, or at least to accept the protagonist as someone just like you. Alice is a normal little girl who winds up in Wonderland. Hank Morgan is a normal modern Conneticut man who shows up in King Arthur's Court. Tai, Matt, Sora, Mimi, Joe, Izzy, and TK are just normal kids who could never have prepared for being trapped in the Digital World. Momonga, Kazuma Sato, Subaru Natsuki, etc, are all just normal people exactly like the target audience who have suddenly woken up in another world.Isekai is about you, the target audience, going on a grand adventure. And while you can certainly give some of those vibes by having your hero be someone who's never left his hometown before, as soon as he talks about moisture farming or bullseyeing wamprats in his t-16, you remind the audience that no, this is a native to this strange and magical world.
