I recently had two very similar conversations. They dealt with, at their essence, what laws are. What are laws? They are rules that must be followed under threat of violence.
It comes down to very basic human nature. To really get in to the nitty gritty read Thomas Hobbes work, particularly Leviathan.. Yes, the one where he says life is "solitary, poor, nasty, brutish, and short", but only in a world with out Government. Also in that book is the thought that a person has a right or license to anything and everything. He goes on to say that there is no such thing as "law" in nature. "Law" only exists when one human being forces another human being to submit to his will. This ALWAYS happens under threat of violence.
Thus, any law that is created by a government is forced upon the people under threat of violence.
This is fact. Not true you say. You have eaten some bad Natto and you are hallucinating you say. Am I? Let us take for example one of the most trivial laws around, jaywalking. It is illegal nearly everywhere in the United States, yet virtually everybody does it. Why? If it is law why does no one care if they jaywalk?
Because it is a law that is NOT enforced. There is no threat of violence, thus people, who do what ever they want to do unless somebody stops them, jaywalk with impunity.
But what happens when I jaywalk in front of Robocop? Robocop, in his three prime directives, just uphold all laws. He tells me to stop. I keep walking. Robocop now must enforce the law. He must carry out the threat of violence, or intensify it, so that others will heed the law. Robocop draws his gun and says stop. I now stop because I know that Robocop will fire if I do not.
This is what laws are. Remember this when you think about trivial things that come up in daily life... Such as smoking bans. Ask yourself if you want Government agents to walk up to a smoker and force them to stop at the point of a gun.
Even better, think about Welfare. Welfare is essentially the government taking, at the point of a gun, money from one private citizen and handing it to another private citizen. If you or I were to do that, it would be called robbery for hire.
