Because it's simple and timesaving, both for you and the firewall,
basically. For example, why write:

iptables -i eth0 -j ACCEPT
iptables -i eth1 -j ACCEPT
iptables -i eth2 -j ACCEPT
iptables -i eth3 -j ACCEPT
iptables -i tr0 -j ACCEPT
iptables -i ppp0 -j ACCEPT

When you could write:

iptables -i ! lo -j ACCEPT

This is an extremely simple example, of course, but still valid. It puts
less stress on you, as well as cpu cycles.

Have a nice day,
