Also, because some of the gates are very far away from baggage claim. The same applies for going to a gate for departure. You would flag down one of the guys with a cart outside and they will radio a person with a wheelchair and they will take you through the check-in process all the way to the plane door with all your luggage. For regular folks those guys can still help at baggage claim if you have a lot of bags that require a couple of carts, they will load them and escort you to the taxi stand where they will load all your bags. I used them for that purpose when I moved here.
