It affects security, but not functionality if you get you
permissions right - which is worth getting right from the
beginning.  But, Safety mainly - it's too easy to screw up your
precious new LFS system if you run as root. Look at the difference
between 'rm -rf ~*' and 'rm -rf *' - not a mistake to make when PWD=/ -
others are more subtle.  I don't think there are any instructions in
BLFS that would cause problems run as root, but then they have not been
checked for that ;-)

Finally Craig, Please read the netiquet section of the LFS FAQ.  You
are a dirty top-poster and a damned HTML mailer.
