If a system has bugs, is it fair to say it's not working?

Typically you just fix a bug, though of course some systems reach a point where a rewrite (either incremental or from scratch) is the only option. I see absolutely no evidence that we reached that point, all arguments are just emotional factoids. I also see no attempts for an incremental rewrite, all people want is to burn the system and hope that something good rises from the ashes.
