The ease comes from necessarily having the decryptor at hand. You can't run the script without the decryptor, and with the decryptor, you can get the source back.

Update: Just to be clear, when people say the script can easily be decrypted, they mean it can easily be decrypted by someone who can run it. If proper encrpytion is used, is can be perfectly safe while attached to an email, etc.
