IF you can receive a station fine without ground connection, then I do not think you need ground for THAT station. I think it all depends on the sufficient field strength for a radio station at a particular location, a good ground can contribute to a much better reception (in a given receiving antenna case) when you wish to listen to a distant station which does not have a strong field 'presence' at your location.
What additional benefit? In your 6 miles away station case probably nothing (I have never had such chance lol), though you could probably use an even shorter piece of wire when you have a good ground. Remember the station transmitter antenna for the AM bands usually works against a big ground system and an isolated metal tower of a given vertical length is the radiator. So in a distant station case you can benefit from grounding because radiated station energy is taken also from the ground, not only from the 'air'.
