TLDR; People don't trust airline and airport with their carry on.
It's all about being sure your carry on luggage will be in the plane with you and not have to be checked in.
People don't want to pay for that and don't trust the airport to get the luggage to their destination.
Also if you do multi flight with different airlines that don't have code share you'd have to go take your luggage and checked in it again, do security etc ... (Depends on the airport).
