It's not wrong, and you've reinforced his point. It's not about "going on a vacation" it's specifically "going on a vacation to <place X>". Something will always be a limiting factor for why you can't have everyone go to a singular place.
Are there other perfectly nice places that you, guy who is in some way limited in your ability/means, could go to instead of the moon? Of course there are. But the moon is off limits to you because you don't have the money to charter the mission there, or the authorization of your government.
