I believe you are confusing raid with backup.
For lots of people the primary role of RAID is as a protection against
data-loss nowadays. Backups just aren't feasible/cost-effective
anymore for the amounts of data involved. Sticking your head in the
sand and repeating that mantra doesn't change that and it isn't
helping.
Well, claiming that RAID will protect your data under all circumstances
isn't helping either. Backups will actually protect against such things as
rm -rf:ing the wrong directory or mkfs:ing the wrong device, etc. Things
that RAID will never protect against.
And I don't see how backups aren't feasable, USB/network harddrives keep
pace with in-box harddrive sizes just fine. Offsite backup might be
trickier/costlier, so you might constrain those to just the data that you
would be really sad to see gone if the house burns down (photo album, own
creations, etc).
