I think it is more inconvenient to log out of one account and then log in to an administrator account in order to run certain commands than it is to use "sudo" to temporarily become administrator.
Other distributions of Linux, such as Debian, require an administrator or root account to be set at install time as well as a user account. Administration tasks can only be done from the administrator account. The temptation is to login as root and continue working as root rather then logging out and logging back in as a standard user.
I mention these things because this discussion is taking place in the New Users section of the forum. As others have mentioned this subject holds dangers for new users. Even long time users can easily mess up.
