Their enemies are as human as him, and they reflect their own weakness and fears. The things people use to stand up for the idea that Batman is fantastical aren't keys in the story: see the example of the Joker's look, Nolan changed the chemical bath (a pulp idea, typical of comic) for some "war paints" and the spirit of the character remained intact. And this applies to almost every aspect in his mythology.
A normal human, even one with unlimited money, could never possibly hope to achieve the very basics of what it means to be Batman, which is perfectly fine
. He's fictional. He's a fantasy. The problem comes with the fact that despite his apparent ability to have 56 hours for every 24 hours a normal human has, every Batman story will inevitably stress the fact that he is human, usually by bringing up some quickly solved weakness that the reader can relate to. This back and forth completely breaks the suspension of disbelief.
Batman, at his core, is a man who through sheer determination, trained himself to the peak of mental and physical condition, learned
mastered hundreds of varying skill sets and martial arts, devised numerous contingency plans for all sorts of scenarios (up to and including contingency plans for his contingency plans), and uses it all to further a single-minded focus to fight crime, and
does this while still being young enough to look good in tights.
In no way is that realistic.
