You forgot to mention the biggest problem with teleportation. How you teleport. Because the question is will your brain  be intact with all the electrolines it has created and all that stuff (I don't know the English terms). Because if that isn't the case you will be as smart as a baby every time you teleport as all your memories and abilities rely on your brain and the electro bonds it has made through out time. So if that stays intact this video is correct but otherwise it is one crappy power to have
