Most distros already sort of elevate the initial users permissions so they can use sound, reboot without a password etc. So this is certainly doable. But doing it systemwise would also allow "rm -rf /" (which is specifically guarded nowadays I know). It's just an additional step. It's also why on most distros the prompt turns red when you're root. I don't have an opinion regarding if this is the right way. I have run as root in the past too. It's been mostly fine.
