Car registration is the first step toward confiscating cars, if the government chooses to do so. Some people drive around yelling political things out their window as a matter of principle, because the 1st amendment of the Constitution allows them to do so, and the thought of logic or reason causing them to restrict their behavior is something they feel should be fought against.
I feel that since the above follows the logical structure of your argument it provides a thoughtful argument for the counter-point by what is called Reductio ad absurdum.
I am not making fun of you, as I can see precisely where you are coming from and know you to be an intelligent person, I just ask that you reflect on the lack of logical cogency that seems present in your existing line of argument. Alternatively perhaps you can reconstruct your thoughts in a way that do not rely on the tenuous assumptions needed to make the logical leaps that you have.
Alternatively, if you were not presenting your own views but simply providing the best possible defense of a known-false stance: I applaud your efforts.
The difference being that cars and driving aren't specifically mentioned in the constitution. Thats pretty much the pivotal point. You could substitute "goldfish" for "arms" and end up at the same place you did with cars.
