Because tapes are best read in a forward motion.

To access a tape randomly would be extremely slow. You would have to continually rewind and check if the data was the reverse of what you were looking for.

It is very impractical and slow.

Tapes are good for storing large amounts of data cheaply and securely. (IE, smaller risk of failure, low cost per TB, easy to store in a bank vault or warehouse.)
