That's a great answer to a question, just not mine. I apologize I may have asked that poorly. This isn't my field of study, honestly if you ever have any Batman questions I'm all over it.
Simply put, laws are created in the USA because we've found something to be wrong or offensive as a society and the law passed (created) is meant to punish that offense?
That CAN be a reason, but it isn't always. Honestly it depends on the individual law, but more importantly, it likely depends on the area of law.
Where what you're saying can be true in criminal law, it isn't likely true with tax policy. Tax policy is just that; policy. It incentives people to make certain decisions in some ways, but also it's there to pay for our government broadly.
Is criminal law ALWAYS the same way? I'm not exactly sure. Some criminal law is old as dirt (murder, for example), while other parts of the criminal are retrospective and made recently, in that a heinous event is committed, we realize there is no law to punish that person, and then we create law after the fact.
So how about this: I always thought, and most pilots think, that the law is "THE LAW." It's black letter, bright line, binary, yes/no, good/bad, but that couldn't be further from the truth. There are many reasons, and many ways that we get to where we are in the ways that we chose to govern ourselves, and almost all rules have exceptions. Almost nothing about the law is, "It is this way because of X." There are almost always two answers, and in may situations more than two answers.
We get there because we have competing interests, and competing ideas for what self governance should look like in our society because very thankfully we ARE NOT all the same. There are those that think that if you steal you should be shot on the spot, and others that believe thieves should be rehabilitated. There are those that think metal illness is a cop out when it comes to sentencing, and there are those who think that non-mentally ill people simply don't commit crimes. Because of these drastically varying views, there are many legitimate answers to lots of tough questions.
Most importantly, there's no way to make things simple. It is impossible to make complex things simple, but that doesn't mean that you can't still eat the elephant one bite at a time.
