They do the isekai thing so then the world building happens naturally as we watch the clueless dork explore the fantasy world and encounter stuff.
Otherwise you have to find ways to explain stuff to the audience when the characters grew up in that world and should already know all about it, so don't need to discuss things.

...you mean worldbuild organically like any other story set in a universe that isn't our own? Countless shows and stories have been doing that for centuries, why should anime get a special little exception?
And for centuries they have been struggling to find good ways to present that newly built world in a natural way. Just because good examples exist doesnt make it an easy thing to accomplish. Bad fantasy stories have also existed for centuries.
You may call it lazy, but you gotta admit that with isekai settings presenting a new world is easy and natural.
And its not like only animes use that. Harry poter, Narnia, Peter Pen, Alice In Wonderland, Tron Legacy etc etc... All have clueless main characters finding themselves in a new world.
Narnia walks through the wardrobe.
Harry Potter learns about the wizarding world.
Hard to do with the axe hanging over your head. "Sorry, but chapter 3 didn't score high enough in our magazine poll so we're killing your serialization."
Too short, append ", but I'm a level 2 demon lord?" to the end.
"Satan couldn't possibly be this cute?!"
The main character is mofe relatable if they can reference pop culture etc
