Interstellar: The Big Shot Retired, Or Maybe She Didn't

[Building a Wasteland Planet, A Big Shot Who Wants to Retire and Live a Carefree Life, with a Touch of Attention-Seeking Personality, Interstellar Wasteland Development, Little to No Romance, Mostly Plot]

After enduring all sorts of mission worlds, the big shot finally meets the requirements for retirement. She happily packs up her little bundle and prepares to head for the wonderful home where she plans to spend her twilight years.

But just as she is about to leave, a malfunction in the teleportation channel accidentally sends her into an interstellar world. In this body, her parents are both dead, and all she inherits is a younger brother she barely knows and a few star coins in her account. The big shot had planned to raise a rich kid into a carefree rich second-generation heir, but she loses it when she realizes she has no money and must build her own retirement home herself.

What kind of cruel twist of fate is this?

The big shot gets off her lazy butt. She may have no money, but she has points. And if she has no happy home to retire to, she'll turn a barren planet into the retirement paradise she wants.

Then the impoverished interstellar culture gradually gains all kinds of content: cuisine, literature, entertainment, dance, and various wondrous systems of power. And it all comes from a tourist planet.
