I have a slightly different view on the matter, indeed :) In a unix
environment there are two kinds of users: "normal" or "regular" users,
and the administrator, or root.

The administrator of the system decides policies and performs system
configuration and monitoring.

If you log into a unix system to do your own work, you are a "regular"
user, and you should not be bothered at all with system configuration
or monitoring.

This is a fairly easy scheme to understand. The problem is that in a
desktop environment, where you are both the only "regular" user and
the "administrator" of your system, the two things might become
entangled.

My solution has always been to keep users and root *separate*,
avoiding sudo altogether, and to ask myself to wear an appropriate
"magic-shiny-hat-with-green-glitters-and-silver-triangle-on-top" (that
I keep on my desk) whenever a part of myself has to become root and
perform a configuration task. I know that whenever I am wearing the
"magic-shiny-hat-with-green-glitters-and-silver-triangle-on-top" I
have to put extra care on whatever I do, since a mistake could cause
the regular users of my system (including the other part of myself) to
suffer unnecessary pain and disruption.

No automagic tool can save you from your own stupidity. You need a
system administrator to manage your linux box, and investing a bit of
time in training a part of yourself for that task, and 2$ in buying a
"magic-shiny-hat-with-green-glitters-and-silver-triangle-on-top" is
really worth the effort, and the price :)
