content: First of all, thank you for writing a thoughtful comment, that actually challenges the points in the article, it's refreshing to see. Also in addition to your point: All IP addresses are registered/licensed similar to a car. This doesn't mean the internet protocol address can't be shared, or stolen, just like a car. When there's an accident, you try to find the cars involved. Sometime it's hard to find the car, and sometime it's hard to find the person that was driving the car, but it's possible.  What he wants is more analogous to mandating some government license scanner in the car so it wouldn't start without, and a GPS on every car that records and uploads all the places you drive to some corporation, which then can be accessed by the government. It's just more Big Brother garbage.
