If you really want to know why you're able to pick up the crack, it's because the game only allows you to interact with items you can "obtain". In order to allow you to dig up cracks and get something for it, I had to make cracks obtainable. Of course, it converts the crack into an ore before you actually get it, but because you didn't put anything in the ground, it doesn't intercept the crack. So yeah, cracks had to be obtainable lol.
