That's the heart of the problem.  Anyone who's owned enough boxes can sit 
there happily running a DDoS anonymously against a target because:

1) The OS/software/default settings for a lot of internet connected 
machines are weak, making it easy to attack from multiple locations.

2) A lot of networks have no customer or egress filtering and make it a 
lot more difficult to trace DDoS traffic because it generally uses faked 
source addresses.

If these issues are addressed then it becomes a lot harder to remain 
anonymous and starting DDoS attacks against targets that can trace you 
becomes a lot less attractive.
