Nicely said, and FWIW, if it were possible to time travel someone from a few hundred years ago to present day, our technolgy would seem like magic to them.
A number of science fiction writers, among others RA Heinlein, have commented on this. "Any sufficiently advanced technology is indistinguishable from magic."
In Middle Earth, magic is their technology. Actually, Tolkien portrays anything more "industrial" than a watermill as far more sinister than the routine use of magic.
