It depends on which side of the fence you sit. If you\'re used to a single user environment (ie: PC/Mac), then your agument stands. If you\'re used to multi-user systems, then running a multi-user OS in single user mode as root is a heinous crime.
Even though I trust myself (despite the fact I once wiped out a 1000+ user /home with rm -rf ../*), I really hate doing normal user tasks as root, and there\'s quite a bit of software doesn\'t like running as root either. There\'s a long established, proper way to do things - making life easy by running as root is a cop out - but I guess these days, on a personal single user system, it doesn\'t really matter.
<rant>there was a time, pre-linux, that having root access was akin to being a god</rant>
