This would break as soon as you met a client without CSS support, or
with insufficient CSS support.

That's actually very valuable semantic information.  If whitespace is
important, then the information about it as such should be carried
with the document.  For an extreme example, consider a block of python
or haskell code - without the whitespace, it's simply a non-working
program.

ASCII art is indeed semantically closest to <img> (it's just an image
done in a different medium), but there's no way to actually use <img>
as such.  <pre> is the second-closest thing if you're going to include
such a thing.
