I think the reason the example in the video is so interesting is that its non-destructive. It only involves bending and the paper and coaster remain intact.

There is a quadratic hole cut into the quadratic paper (which I would clearly call "destructive"). It is just not shown in the video how the quadratic hole is cut into the quadratic paper. If this argument does not convince you, here is another one: Also for stepping through a postcard after the hole is cut it is just bending the paper.
- Too 9y agoEhh. They way you initially cut the paper constraints how you later can fold it. If the square was cut any smaller you wouldn't be able to fit the coaster through no matter how you try to fold the paper. The square and its size is a constant in this problem, using a scissor to make the square bigger after its given to you would be considered destructive. In the postcard problem there is no such constraint as you are allowed to cut in whichever form/size you want.
