The command noclip disables teleporting back into valid position when you are in a invaild position.
So if you use noclip and setpos, you can teleport anywhere in the map for a indefinite amount of time, without being sent back.
You can't idiot-proof things, no matter how much you try, cause in the end, the world will just make a better idiot.
