Hard disagree. FS permissions take like 5 minutes to explain and then you maybe need another 30 minutes in total to try around and get a hang of it. I've given up on selinux every time I've tried to make sense of it. Open 3 different tutorials, have 3 totally different approaches to it.
I guess if you only install core packages on redhat and never touch a single config file it might work OK even for the average Joe.
