Copyright law doesn’t really care about what you do with copyrighted works as long as you don’t make what you did public.
Au contraire. The only reason you can rip a CD and put it on your computer is because of the doctrine of fair use. Without it, copyright law most definitely says you are not allowed to make unauthorized copies, period. What you do with them is not relevant.
It’s a simplification of copyright law (which is bloody complicated) that is, in general, true. (As you yourself said, you can rip a CD. It’s perfectly legal. Uploading said ripped CD to a server and publishing the link is not. Fair use is part of the copyright law. The only reason you can rip a CD is because of copyright law – just what I said.)
