Agreed, it's cool that you can reverify a torrent from 3 years ago and make sure the data on your disk isn't lost or damaged.

That's useful if you did not prepare for that eventuality. But if you do want to store data long-term it's better to generate error-correcting codes like PAR2 so that you can actually recover partial errors without having to rely on seeders being available - and when you do that you no longer need the torrent for verification.
