Simple scenario - say I use p2p-type program (like azureus or something) 
or, worse still, have a rogue code/process/program on my machine (that I 
know nothing of) which tries to communicate from my machine to IP 
addresses which are banned (i.e. try to "call home") - in that case I 
would need these packets to be dropped without question.
