The problem is that experiments into this by Google have concluded that radiation hardening is unnecessary. HBM memory far surpassed their expectations for survival, exceeding 5 years in their simulated proton beam on earth. Localized shielding for consumer equipment is more than enough, especially combined with ECC.

Solar power and power dissipation are similarly solvable. The only bottleneck currently is launch costs which is why it’s expected around 2030 is when these DCs will explode

So it is not outright stupid, just has a few extra costs.

So again, what's the economical benefit? Because you surely have no power and dissipation problem down on Earth, so why add a whole rocket launch into the equation? Because big fire goes brr?
