This is not might makes right. This is might makes possible. This is might precedes questions of right or wrong.
Without might, law is not possible. Might is a precondition for law. Without might, there can be no law.
Just because people think that the law has something to with right and wrong doesn’t mean it does. People can think any law is either morally just or morally unjust, but without the power to enforce the law, it doesn’t matter what they think it is, it’s not a law. And lawmen can think their acts are morally justified, but that’s irrelevant. If they didn’t have the might to enforce the law, it wouldn’t matter what their values were.
For instance, you could pass a law yourself right now but if you lack the might to uphold it, it won’t be a law. Conversely, if our government passes a law and can enforce it, it’s a law whether you think it’s right or wrong.
People can certainly pass laws that are consistent with their values, but the law itself has nothing to do with right and wrong. It has to do with might. Might cannot make things right or wrong, it can simply make them so. People can inject their own set of moral values into any set of laws and declare them either just or unjust but the actual mechanism of law has nothing to do with right and wrong.
We must separate the values inserted into laws by people from the actual functional mechanism behind law, which is the use of force to uphold rules. We must also separate ourselves from the idea that laws require moral and/or logical justification. They do not. Laws simply require that someone has the power to enforce them.
EDIT: As an answer to another poster: if you really look at the way our common law system works, it’s all based on precedent, so it’s inherently conservative and inherently dedicated to the status quo. What was held to be law yesterday will mostly likely be held to be law today and tomorrow unless the court overturns precedent, which is not as common as the court upholding precedent. I personally tend to favor the status quo myself. I don’t like too much change. I like things to be predictable. So I find myself naturally drawn to the law because it facilitates my personal preferences.
