My assumption would be that it’s because we don’t really look at mirrors per se but rather the reflection in them, so the definite article is indicating the fungibility of the mirror itself. This total speculation on my part though and I might be totally wrong.

I like this interpretation. Fungible is a great way to describe the function of the physical mirror in the phrasing.
