Thor isn't a title.

Yes it is. As part of the Avengers all of there Superhero names are titles that can be passed on. While pretending to be a human Thor goes by the alias of Dr. Donald Blake. But in the eyes of the public each superhero is just as much an office as it is a person. Captain America had a successor who took his name after his apparent death at the end of the Civil War storyline. Scott Lang took over as Ant Man from Hank Pym after his psychotic break and the Yellow Jacket episode. It just so happens that Thor is unique in that his superhero name is his birth name and his mundane identity is made up while most everyone else is the opposite.
