If a credit card gets stolen they have access to the CVV number as easily as the 16 digits

Credit card numbers can be quite easily generated, actually. They follow a very specific pattern, with the first four to eight  numbers describing the issuer. Then the rest of the numbers are the account number. Except the last number, which is a checksum. So someone who might want to use someone else’s card online could easily generate a valid card without much fuss, since the options are not that many. 

So the cvv is an identifier that’s specific to that card, to make sure the user is the actual owner.
