You are altogether externalizing the cost of carbon dioxide emissions that humanity has to pay for. The resulting global warming is not a joke. The heat problem cumulatively is bigger on Earth than it would be in space.

Cost = emmissions

[DoctorOetker]

No, cost is not directly proportional to emissions.

Heat emission in space is not problematic for humans

[xnx]

Are you counting the emissions to get the datacenters into space?

[OutOfHere]

That's an environmental and financial cost, but it's a one time cost. For datacenters on Earth, the emissions are continuous.

Are there going to be self sustaining server factories in space? The hw needs updating every few years.

[OutOfHere]

How do we bootstrap to the point where we eventually have factories in space?

If it were up to me, I would be researching and optimizing non-chemical propulsion, also green synthetic fuels for launches. Unfortunately, we will have to leave that for some firm other than SpaceX to develop.
