They've got to learn how to 1v2 eventually, or at least learn that if there is a jungler and they can't 1v2 they should stay out of top. You can say "no one buys wards at my level" too if you want, but the point is you might as well use every level you get to learn the game, jungle included. If jungling causes your team to lose, not the end of the world. If it teaches everyone involved to be better players in the future, it was worth it.
