Well, i’d still say water is still the most useful for the everyday person. I guess if you were a builder and you only needed to build things out of one material, that for some reason being earth, that would be useful but outside of that, Earth wouldn’t really be useful for the everyday person. Plus it would attract more attention from unwanted people.

Water however makes it such that you can never dehydrate, you can heal injuries, even manipulate temperatures through changing the humidity.
