It makes more sense when you remember it's not a computer program and the things that are written in the law are not the things that will actually happen in the way that "if(foo) bar;" makes bar happen if foo is true. It's more like a book of excuses you could use for why you didn't do your homework.
Then the other side also has to bring an excuse for why you were supposed to do it, and if the principal thinks their excuse is better than yours, you get detention.
If you tell the principal "I don't have to do my homework because work means employment and it's illegal to employ a minor" you'll get detention for not doing your homework and extra detention for being a smartass.
And this example is not just due to people not taking the trouble to write fully specified rules. I don't think such rules could even be written. You can just do your best to cover the cases you can think of. The complexity of society is incomprehensibly vast and constantly changing, and the law has to have wiggle room to account for it.
You don't want fully-specified rules because a rule with strict boundaries has loopholes. You actually want a clearly allowed area, a clearly disallowed area, and a gradually increasing gradient of punishment in between, so that a small change in behaviour produces only a small change in punishment, and avoiding punishment requires a large change in behaviour.
Exactly!
