Why has no satellite ever been put into lunar orbit at an extremely low altitude, like a couple miles above the highest landmark?

There is no atmosphere to slow the satellite down afterall, and I imagine it would allow for much more defined pictures of the surface, using a properly timed camera with low exposition time...

The first and most important reason is that there is no need. Since there is no atmosphere, there is no distortion of images. We can take pictures just fine from far up. In addition to that, congress has decided that high resolution pictures of the lunar surface aren't very important, so therefore there aren't a lot of missions that do that.

Secondly, spacecraft orbit determination is tough. Around Earth we know the field fairly well, but around the moon, things get tricky. You don't want to crash a satellite into the moon just because you wanted to get fancy. There would be no living that one down, especially when a higher orbit would have been sufficient.
