I imagine that for many people, that is far less expensive than needing to buy everything they might need once a year, find storage for it, and go get it/return it/ to that storage. It quite possibly this wouldn't be convenient for something like a set of wrenches which you might be able to buy outright, but for someone who needs them only once a year and has other things to borrow, this could be very reasonable.
