By definition, a data center in space is remote, self-reliant on electrical power and doesn't use potable water. These features require technical solutions before they become practical, and once one has cracked those challenges, they have disarmed all the push-back arguments people have raised against data centers. It's telling that the data centers want to build-out near population centers, i.e. where someone else has paid for fiber, grid and water infrastructure; it's a good old fashioned raid of the commons. This is why no-one is pushing for building data centers in locales with 0.2 people/sq mile with no one to subsidize the costs.

Likely because the AI companies that are going to use those data centers have the absolute worst marketing imaginable. "We're going to take away your job and might accidently kill everybody on earth!" It's no wonder they get pushback.
