It's natural in the sense that you have it if you are the only person on an island somewhere, assuming there's no aircraft or satellites going overhead. In that situation you could literally say anything you wanted, as long as you can collect food and water and not die of some other cause before you finish saying it. Kind of goes for other things to a lesser extent, for example you have total privacy and there's no one there to take away any guns you have, but you do have to think about other people more in those cases, as the island thing is just a thought exercise.
