Well how would it be a ripoff if its a common and useful feature in nearly all big games that have stacks of items or are survival/collecting style kind of games
Let's say it that way, if you build big and you get over 5-10 chest full of thatches when you farm wood, you sort your chests or you move items from one floor to another (for example from floor 1 to 10) it is very time consuming to drag them with the cursor, especially when it sometimes doesn't move the stack due to not selecting the slot because of some reason.
