When we're talking about creating powerplants equal to roughly 5% of the insolation of Earth, I think we're sci-fi enough to discuss orbital datacenters or Mars datacenters or Jupiter fusion candle datacenters.
Using an entire Mars only nets us about a 2x multiplier for our energy expenditure budget. Then we need four planets to double it again. Exponential growth is a bitch.
Thermodynamics and the tyranny of exponential growth are going to win this battle every time, regardless of the unobtanium technology you try to invent.

We don't need to care about cooking Mars.
I’m assuming you care about melting the GPUs in your orbital datacenters.

The problem at hand is not just getting rid of heat however, it's getting rid of heat without cooking the Earth. I still fail to see how generating the heat off planet fails to solve that.
