Forget all the technical details of trying to actually teleport. The fun stuff is imagining what you could do with your new-found superpowers.
YouTuber Tom Scott has examined some of the potential logistical difficulties and opportunities that would go along with teleportation. For example, the surface of the Earth is moving at different speeds in different places, which would create some problems if you shift latitude while teleporting.
There's also lots of potential for good or evil: you could crash an asteroid into the Earth, or potentially create a perpetual motion machine — at least, if it wasn't for those pesky laws of thermodynamics.
