I've seen more compromised boxes than one can shake a stick at. There's all sorts of reasons that blocking egress is a great idea. Compromises are usually automated bots, and no, they're not smart enough to bring down iptables. Even if it's a human that's pwned you, it's frequently a stupid human, or a lazy human. It's just good practice to practice security in depth.

Or a non-privileged account is accessed and the kiddie just wanted to run an eggdrop bot. Plot foiled.
