It's only a bill as yet, not law. Hard-right politicians in America introduce insanely right-wing bills like this on a regular basis, knowing they'll never become law, but doing it in order to get a bit od publicity for their bonkers ideas. I remember a few years ago, someone introduced a bill into one state's legislature which would have required all adults to carry a gun in public, unless they hasd a special licence exempting them, and the licence would have cost them money to obtain and renew. Naturally, it failed to become law, but it got a bit of publicity for the gun nuts.
