That's not so enticing when I could get 3 16TB hard drives for half the price, with a full copy on each drive plus some par3 files in case of bad sectors.

You could, it’s really a question of what your needs are and what your backup strategy is.

Most people don’t have that much data to back up, I don’t backup movies and shows I download because I can always rebuild the library from scratch I only backup stuff I create, so personal photos, videos etc.

I’m not using a tape backup either, cloud backup is enough for me its cheap as long as you focus your backups to what matters the most.
