When I was about 21 an unattractive, overweight woman said to a friend and me, "I have the right..." (We were in college and she was a busybody sticking her nose into what was none of her business.)
I said to her, "You have no rights."
And she didn't.
It was John Locke who came up with the concept of our having the "natural rights" to "life, liberty and property." It made it into the Declaration of Independence as "life, liberty and the pursuit of happiness."
Now those ideas are what works best for everyone, for society, for the purpose of government. Unfortunately, those "rights" are just ideas in our heads we impose on reality.
That's why that woman had no rights. If I had beaten her or killed her, she could not have stopped me.
"Rights" are ultimately based on violence or the threat of violence. Nothing else.
Fortunately most people are good-natured enough to subscribe to "live and let live." Most. Some don't, and those we define as criminals. They steal, they mug they murder, they rape.
If someone wanted to, they could kill a lot of people before they're stopped - by violence. Think Ted Bundy, and how long it took to catch him.
That is incredibly scary, if you think about it.
There is a hierarchy of ideas, from the bad ones to the good ones. The good ones lead to the greatest eudamonia for people - those old qualities of the Good, the True, the Beautiful. The bad one lead us straight to hell on earth.
The bad ones, when implemented in society, cause all sorts of mayhem - chaos. When government subscribes to those ideas (which is often called "the Political Means") we get the worst catastrophes that exist.
The good ones lead to peace and prosperity (I've heard those called "the Economic Means").
In other words, bad government is the worst thing ever. And it always get out of control. Think Ted Bundy multiplied by millions of times.
Ultimately, then, everything is defined by ideas.
