Laws don't keep people from taking tangible items, they only punish afterwards. The only thing that stops someone from taking something tangible from you is your ability to stop them. Nothing stops someone from making a copy of information they already have.

Think of all the "priests" throughout various cultures in history. Think of why encryption exists. Think of why the CIA and NSA exist.

Secret versus public knowledge. They are two entirely different things. This discussion is about intentionally published knowledge.

Wait, by (1) you mean if rape, murder, theft ever become the common case, it will be OK? You know, like when it happens during wars?

Even during war none of those is the common case. That's why we prosecute people for those crimes in times of war too. If those things actually become the common case, we can cross that bridge when we come it.

But you know what is rivalrous? The food, shelter and clothing creators need to live to create new works.

Yes sir, Mr Valenti!

Would you share here all your private information

Again, secret versus public.
