POW is very important, without it I wouldn't have had any problems destroying the network totally and quickly. Because protocol allows very efficient attack amplification. Even with POW I can do serious damage, but I'm required to run cluster of high end servers. Without POW I can use any random computer to waste whole network using network propagation and attack amplification.
