I am not a very expierenced Linux user, but as far as I know, your 
description of sudo is not right. Sudo does not grant full root 
privileges by default, but is a way to grant users specific rights to 
accomplish specific tasks. For example, "Mary" may use sudo to control 
the mailserver while "Kyle" is allowed to control the print server using 
sudo. "Kyle" can in no way manipulate the mailserver with sudo because 
his sudo rights does not allow this. In short, sudo is highly 
customizable in respect of the given rights. Seems to me that you are 
mingling su and sudo.

You should really read the given links from recent posts to learn the 
way sudo is used in Ubuntu since you seem to have some misconceptions 
about this.
