You are very confused. The reasonable person standard has absolutely nothing to do with your initial post where you quoted it.
>If your hypothetical where you could use the printed law as passed by legislators essentially as a lookup table, lawyers would serve no purpose.
What the fuck are you talking about? The stuff I see people here say about the law is INSANE. You don't need a lawyer in the US if you are an individual person, you can represent yourself. What the hell does any of it have to do with a lookup table? I've never seen something so deeply confused and misguided.
