I have external parity for everything with rsync. I don't have any storage that isn't matched with external backups. Fortunately I've never seen any bitrot or had a drive fail on me since I tend to replace them before they do. And yeah, I could add in some extra HDDs for RAID, but this is more a personal choice because of how much I hate SATA.
Filesystems like ext4 are because I value boring and rock solid stability over semi-experimental status of modern filesystems with all the features.
