I think I’m normal teleporting scenarios it doesn’t allow you to teleport into ‘objects’, though obviously there has to be some exception for air or it’s basically worthless. I don’t think I’ve ever seen any scenario where you displace anything other than gas?

Hopefully it’s a7 inch gap, if it’s 7 inches from center mass you’re not really fully shifting position.

Sure, but when did that happen? After the first board was replaced? As soon as the first board was damaged?

It seems obvious that the whole thought experiment is just semantics. One of those things that interesting to think about the first time, but after awhile it’s just illustrative to point out how we just define things imprecisely and that I’m almost all cases it is far more convenient and practical, but if you look at anything from the right perspective, the lack of precision stands out. Even ‘walking out of a room’ doesn’t have a perfect description if you slow things down far enough, but practically it’s pretty useful to describe it as a distinct event.
