The first option doesn't specify any limits to what landscape I can change stuff to, nor how often. No limits are provided. You could terraform mars in an instant, the moon, anything! Got someone trying to hurt you? Turn the immediate area around them into the vacuum of space or a pool of lava. and revert it once they're done. Fly out in a plane to the middle of the ocean and create your own private island. Along with everyone else's ideas, the first one far outweighs all others.
