People keep saying this but I think it's horseshit. Picard was obviously capable of doing anything he wanted in life. If he had really wanted a family, he would have had one.
He was forced to live out decades in a preprogrammed environment. If that's not considered mind rape I don't know what is.
I think you're missing the point.
First of all, it wasn't preprogrammed. The parts were there, but what happened flowed from what Picard did. I doubt there were specific events programmed in, except for the whole"Our sun is dying" thing.
Secondly, it's about how, yes, even though Picard chose his career over a family, the lack of a family is something that still affected him. Just because his career was more important to him doesn't mean that a family was meaningless to him. This episode gives him the chance to not have to worry about his career so he can have that family.
