I think honestly this is a valid critique even as a fan of space exploration and a “luxury space communism” wisher.

I think visiting other planets has given us some scientific knowledge that is valuable in and of itself in a quest for self-improvement and exploration - seeking of answers to our questions and new questions. I would hope, that this one day can become a worthwhile pursuit for the collective humanity as a voluntary quest, but obviously it’s a misallocation of resources when there are capitalists to be eaten first and it’s only done as a way to one up the rival empire.
