This matters when you're an op in an IRC channel and someone joins the channel, starts spamming racial slurs, so you ban them, and they respond by DDoSing you.
If I had a dollar for every time it happened, I'd have $2, which isn't a lot of money but it's pretty annoying that it's happened twice. The first time, they only ran the attack for a few minutes. The second time it happened, they ran it for over an hour. Releasing and Renewing my WAN IP didn't stop the attack, because I still got the same WAN IP. I had to call my ISP support and spend way too long on the phone trying to talk to someone who knew what I was asking for to get a new IP address before I was able to dodge the attack.
Using AWS, I can configure security groups so that my VM never even sees the packets from a DDoS if I've configured them to only allow connections from my home IP.
