Those CD's would not be a true Audio CD then. They could also be scratched or a version of an Enhanced Audio CD that is not Mac friendly. Maybe a drive issue too.
The main reason that there are no issues with copying/ripping CD's is because the format doesn't allow for any copy protection. Sure, there are some bits you can change around to try to prevent a copy of a copy (duplication). Those are easy to get around. Redbook Audio CD's are a standard format that has to be able to be played on even the dumbest of CD players. These CD players (some probably still from the late 80's) will have no way to read an Audio CD with any type of copy protection. That doesn't directly make it legal, just possible with no consequences.
At least with DVD's, there has been some form of copy protection from the start - Macrovision. The thing that scrambles your picture when you try to record a DVD to VHS. The "computer" on DVD players is smarter than that of CD players and allows for multiple forms of copy protected material to be played back without issue.
