The reason it is possible to spoof caller id is so that you can receive return calls to an incoming number when the outgoing is not that same number. I use it in my case because I have a Google Voice number, which has been my number, originally a landline, since the late 90s. I never have to tell friends what my new number is each time I change phone companies. With spoofing, they see that Google Voice number as the source of the call, and correctly call back "my" number instead of the number du jour.
