I see, and who is to be the interpreter of that?

You, me, and everybody. You have a moral obligation to resist laws when you perceive them to be immoral. This was a pretty big part of the civil rights era for instance (not to say that reusing hardware is so morally important as that, but it neatly demonstrates the principle of not resolutely adhering to all laws.)

People are. And history is the judge.

Luckily, people aren't computers and don't need an interpreter. Use your judgement, your ethics, and common sense.

So... why do we need laws then?
