OTOH SpaceX has a pretty good history of undercutting the industry on cost. If Starship full reusability works I would be very surprised if it only lowered launch costs by a factor of three. Of course it's not guaranteed to work, but clearly SpaceX's orbital datacenter plans are predicated on Starship working.
SpaceX created reusable rockets that can fly back to the launch platforms and land gracefully. Hard to blame people for becoming fans. Before them stuff like this only existed in kerbal and sci-fi.
Accepting everything they then do, forever, even when it's obviously nonsense, is what gets you called a "huge batshit crazy fanbase of boot lickers".
This "idea" is great party conversation. It's probably doing a great job of shoving around the Overton window, too (perhaps the real goal here?). It's, uh, not realistic, and anyone who is seriously "all in" on it (you're allowed to consider it and to dream, that's not the same as being all in) is not worth taking seriously no matter how much of the oxygen in the room they're using up.
