I guess when I think of using a tree stand several uses come to mind. Climb the tree with hooks and put in the stand. You get done and climb back down using the same hooks. The next day you go back and so on. IMO if someone wants to put up a tree stand do it with the conventional climbing aids like screw in steps or strap on ladders. If it is a one time shot then I agree it probably wouldn't harm the tree other than cosmetically. I also believe there are several safer options for a person to use when they want to go up a tree.
