Part of my reasoning is that "law" protects bad guys from real consequences. It is "more illegal" to kill someone who is breaking into your car than it is for him to do the breaking in. This makes bad guys bold.
He breaks into your car in spite of the law, when he might not dare do so in the absence of the law.
I suspect it might be the same in other areas as well.
How do people drive in spite of the law, and how might they drive in the absence of laws regarding driving? I know that I can either drive well, or I can obey the traffic laws. I can NOT do both. How many other problems will be solved once humanity gets over this addiction to statutory "laws"?
