I can't see that the people in question were actually hurting anybody.
I am not particularly happy about people driving around around in illegal vehicles with suspended licenses - my guess is that they are none to careful to keep up their liability insurance.
That means if they hit you or me, we can be impoverished by their actions.
The point of requiring me to register and insure my vehicle and have a valid drivers license is to protect other people I may injure in an accident. I am not required (at least in NC) to require collision insurance, which protects me, but I am required to have liability insurance, which protects others.
As far as the RKBA issues, you may be correct. Though - to be honest - I am a little nervous as to whether folks who are incapable of operating a vehicle responsibly should be carrying around lethal weapons. I can see folks deciding not to operate vehicles, etc. But if you decide to operate a vehicle and cannot do so responsibly, I don't know how comfortable I am with you carrying around a 1911.
Notice that is a statement of my discomfort - not an argument that folks should lose the right to keep an bear arms due to a traffic ticket.
