I've never seen this argument brought up by anyone serious, not in the above post, not in the space datacenter blog by Google, etc.

The main benefit is that solar panels go from a complicated mess of batteries + permitting to a very stable, highly efficient energy source.

Search "data centers in space" and it gets mentioned constantly. Cooling is even mentioned in this announcement. It's not explicitly described as an advantage for putting things in space, but it states that terrestrial data centers "require immense amounts of power and cooling," and that heavily implies that cooling is less of a problem in space.
