I recommend reading up on the results of Google’s project suncatcher. IMHO the results have provided a roadmap to space DCs with the only blocker being launch cost which are targeted to become economically viable in 2030s; sooner for spacex because they can lower their margins to zero or even negative for the launch itself.

Whenever I asked someone to dig down into "against the laws of physics" arguments, they turned out to instead rest on a pile of tacit and pessimistic technological assumptions.

Perhaps you could explain in detail why you think the laws of physics have to be violated for space data centers to work.
