You're going to get downvoted because you're posting this in a forum of largely programmers, many of whom believe that every problem is essentially a programming problem, and that the law could be computer code if only the spec were well-enough defined.
In reality, "defining the spec" is the entire purpose of having a legal system in the first place. A nation is a machine that is evolving its own state. There's no outside "programmer" who can observe and define the entirety of the desired state. (Unless you believe in an active interested conception of God, perhaps.)
The legislators, lawyers, and judges who tell us what the law is, are part of society too--and that's why the law changes over time. It's supposed to change over time. The law constrains human behavior, but it also reflects human behavior, so the state of what's legal right now exists in a weird state of superposition between the two.
But, the fantasy that one is outside of, or separate from, society is a popular one--seen most clearly expressed in the libertarian creed, but popular in Silicon Valley too, at least from a business perspective. What do most tech companies want from the government? To stay the heck out of their business, stay far away, and don't bother me. That includes lawyers.
So you're going to get downvoted here, but I don't think that means you're wrong.
