Worth noting that teleportation also necessitates the destruction of your previous "you" along with creation of a duplicate "you." Even if it was workable without the massive amounts of time or energy stated in the article, there'd be some obvious ethical dilemmas - the process kills original you in the process of copying and recreating original you.

Interestingly, in the long run this probably doesn't "matter" for anyone else or even your role in the universe, because there's still a perfect copy of you doing exactly what you would have done, so it's like you didn't die. But you did still die... and dying is rather scary for most people.
