Good points.  To me though, the risk is greater to my data than
to /bin.  /bin can be rebuild in 10 mins, /home can't.  (On a single
user system, the only thing in /home is the user directory)  So, while I
agree with your premise that privilege separation, selinux, ACLs, etc
all add to integrity, I think they only do to a minor point in the grand
scheme of things.  Privilege separation, selinux, ACLs, etc., don't
protect /home/jimpop, the area that is important to me (and presumably
normal Desktop users)

First, I don't run as root and have never stated that I have.  The point 
of my involvement in this tread was to question the reasons behind a 20
year "wives tale" and to get at the root of the reason(s).  To say that 
all systems everywhere should have a minimum of 2 accounts (one privileged
and one not) is too broad a brush for me to paint with.

I don't blindly trust the software I use.  There is not practical way to trust
everything in a Linux install.  I do trust the distributor, and I trust
their security updates (to some extent).  However, this issue is really not 
relevant to a non-root install (at least for me) as the critical part of
my laptop system is not /bin, it is /home.  Anything in /home/jimpop can be
destroyed by any application I run.   So, application trust is necessary 
unless I personally take the time to test and verify all the applications 
I use.
