I can see a lot of reasons, but it's an answer requiring lots of
thought. I'm not certain that it'd be an advantage. Some things that
come to mind are:
1. non-gaussian interferers would be reduced by the spread processing
gain. (Yay!)
2. With a long enough code you can discriminate against multipath
(skywave.) as well as Loran - really limiting diurnal shift.
3. With a high chip rate you can potentially get really fine time
resolution.
4. Most of the processing goes right to bits - Moore's law becomes
our buddy.
