Because it requires fewer key strokes.

Because IMHO, emacs (and any software) should do as little as possible by
default, or at least easily allow itself to be configured to do as little as
possible. I think it makes the most sense that switch-to-buffer takes you back
to the last buffer you were visiting by default, without doing the extra work
of preferring buffers that are not currently visible.

No, quit-window buries the buffer that you leave, even though it switches
directly to the previous buffer on the top of the buffer list, and so it cannot
be used to alternate back and fourth. Switch-to-prev-buffer seems to do the
same thing - executing it twice does not return you to the buffer you started
at. Besides, using these functions would require adding an extra key in
addition to 'C-x b', and keys are at a premium.
