But this isn't an intrinsic downside, which is what I was asking for. James pointed out that superspeed necessarily implies a super slowdown from the speedster's perception; that's intrinsic. Similarly, so what if you have super-strength if you don't have the correspondingly fine muscular control? That's intrinsic. Contrariwise, if you want to posit superfine muscular control along with super strength, that's two different superpowers, not one.

So what are the intrinsic downsides of teleportation?
