Elon's not doing any of that and never will lol. You're vastly underestimating the cost and complexity of doing anything in space.

Sure, an asteroid theoretically has eighty quadrillion dollars of whatever, but you're going to spend ninety bajillion getting anything there and back, plus you'd ...well, crater the market even if you did.

We're not hurting for heat sinks. There's the entire ocean to work with, for one.
