Not everyone is going to have an aquarium so thickly planted with high-growth plants that an electrically-powered filter is unnecessary. That's why it is important for filter media within an actual filter have time to grow and develop bacteria that can process ammonia. For example: exactly what the OP is trying to do.
A heavily planted tank is already cycled. Of course, people can still choose to follow a set of old procedure that is no longer required.
