Hard disagree. sudo isn't a proper security mechanism.
That's not the point here ^^
If you have some privileges for a good reason (let's say you are netw admin or whatever), and you need to use them use sudo instead of being always root.
This way it limits error that you can do while being root.
It's a very simple limitation of course, it's just a bit better ^^ It can't protect you from yourself :p
