So it only has utility for those who believe that "non-magical" dwarves, elves, halflings, orcs, dragon people, cat people, half-devils, half-angels, lizard people...
..that live in a setting often cosmologically described as planes of existence
..with active and various deities, fey, and creatures from beyond the stars that meddle and plot
..where places can be cursed or hallowed, and items enchanted or animated
..should all have the same basic limitations they do in the real world, because no one has applied the word "magical" to any abilities they may possess?
I'm probably just going to have to take your word for it.
