This is bogus on two levels: One, you are conveniently focusing on enforcement and ignoring that patents in the US are laid out by the "highest law of the land" i.e. the constitution. Clearly, that makes it law.

But secondly, your attempt to claim that civil litigation cannot land you in jail is also plain false. If you loose a civil case and do not pay the penalties (or choose to not even appear in court in the first place), you will, in your words, still have: "the government with it's endless ability to spend money and the police are involved." and "it means violation means the guys with the badges can come put you in a cage."
