As unlikely a scenario as finding a Talaxian colony so far from Talax was, I suppose it was good that Neelix found some of his own people. If he had continued on to the AQ with Voyager he most likely would never have seen any of his people again.
Would he have found himself lonely on Earth or wherever he chose to settle in Federation society? His friends on Voyager would either be reuniting with loved ones or facing unknown futures* or both.
*Unknown futures like the status of the Maquis or whether Janeway was in trouble with Starfleet because of some of the decisions she made.
However I do believe that the crew of Voyager became like a surrogate family to him. He genuinely loved them and they loved him.
