DDoS attacks don't just hurt the target of the attack. If any link on the path to the target is overwhelmed by the attack traffic, all users of that link are affected. Large attacks are hundreds of Gbps - a datacenter with 100Gbps of internet connectivity would be effectively offline. A datacenter with that much connectivity will likely host more than one site. I know you aren't advocating that other sites be taken down, but that is the effect of allowing DDoS against a site. Perhaps you don't mind collateral damage but it should be acknowledged as a consequence of your suggestion.
