In both Generations and the Inner Light the writers played with the idea of contrasting Picard's life alone in Star Fleet with a life he could have had being a family man, even implying that that life is what would have truly fulfilled him. But is there any reason to think the life of a family man would be remotely appealing to Picard? Picard seemed to express an actual dislike of children which I don't think would be unusual in a man like Picard. Someone so focused and reflective and disciplined like Picard couldn't stand to having screaming brats around him. Secondly Picard was presented as a very driven man since his childhood. He had a goal, to be in Star Fleet, and that is all he wanted. Why should any alternative life have to appeal to him? Lastly Picard himself didn't have the best of childhood's and familial attachment never seemed that important to him. Shouldn't Picard's fantasy life in the Nexus pretty much been as the captain of the Enterprise forever?
