Well how *exactly* does running *as root* defeat *most* of the security of a linux system. Sorry but that is BS.
No, it is not.

Virtually any exploitable point allows an escalation by way of further exploit.
That's correct. However, this should not imply that just because there exists a possibility of escalation, we should not have multiple levels of security.

Just because you have a safe, does not mean you leave your door unlocked, just because you have a lock on the door, does not mean you don't need a fence ...etc

If and only if, it is possible to ensure (to 100%) that no exploit can be escalated to provide root level privileges, is it reasonable and logical to claim that not using root, is "safer" than using root.
It is not possible to ensure 100% security. That's the nature of software ...or any sort of security for that matter ...think about it. However, we do tend to minimize damage by building multiple levels of protection.

Not running as root is "safer" than using root, when using tools that do not need all the privileges that the root user enjoys. For example, when a bug in gnome-panel running in the context of a normal user is exploited, the attacker would have to exploit yet another level before gaining total access to the system.

I suspect that you understand this bit, but don't somehow agree with the concept of "sandboxing" as a way to limit damage, in which case, would you be kind enough to tell me your email password ...after all i don't know anything about you, so what's the worst that could happen ? :)

cheers,
