The copies thing is a really only for laptops, where the likelihood of redundancy is very low (there are some high-end laptops with multiple drives, but those are relatively rare) and where this idea is better than nothing. It's also nice that copies can be set on a per-dataset manner (whereas RAID-Zn and mirroring are for pool-wide redundancy, not per-dataset), so you could set it > 1 on home directories but not /.
