They use that option because that is, most likely, the actual reason. But people in the West need a reason for some reason. It can never be as simple as "I just wanted the protag to be male."

So they have to come up with some reason and it's always some dumbass one because they never really had a definitive reason for it before. See: Final Fantasy XV.

They didn't have a reason aside from "this is the story we wanted to tell" when asked why they chose for an all male party. Then, they had to come up with a reason and it was equally as dumb and inane as the Persona one above.
