Stealing luggage is so rare it’s meaningless. If you are really worried about your luggage, the easiest way to steal someone’s luggage is at baggage claim and just knock the lock off after they leave the airport.
There isn’t a ring of thieves at the airport stealing your clothes.
Lost luggage and delayed luggage is a bigger concern.
