My mom, who's a lawyer, always told us that laws don't matter, what matter is how hard they're enforced, and we can simply ignore laws that exist but we know for a fact they're not enforced (or not enforceable).
I once had small talk with Lawrence Lessig after a conference of his, and when I told him that he was visibly shocked, as if I had told him I was raised to be a criminal.
Now I'm not sure what to think anymore.
