Not sure I agree. Plenty of people recommend using one-way hashes for passwords: http://stackoverflow.com/questions/2549988/whats-the-recommended-hashing-algorithm-to-use-for-stored-passwords
One way hashing can be done using encryption algorithms instead of hashing algorithms. You can try more than a million different passwords per second with sha1 and sha2. Not so many with one way two fish encryption with a 100 rounds.
