My answer to this question is always teleportation, including my clothes and anyone I’m touching (and their clothes). And the ability to not appear inside solid objects. No more traffic. No more passports or visas. No more long multi-hour drives or long haul flights.

Have fun figuring out the point of reference of your new powers. It would be hillarious if it was not the nearest grvitational well. Earth moves, the sun moves, our galaxy moves. Watch it be not the most obvious thing, and you teleport into empty space.

…and that always comes up as a response. Ok fine, I’ll add another line to the fine print: The ability to teleport at the exact place I want to be. If you want to counter that still, then make it places I’ve been to before. It will limit my destinations, but it still saves me time and effort. I’ve never been to France, but I’ve been to Germany, so that still reduces my travel from almost a day of flying and layovers to a train ride.
