Now there is an incentive to go!
Diamond, like gold, is valuable because it's rare. Accessing cubic
miles of diamonds would trash its value.

Wrong. Diamond is light, hard, strong and has very high thermal
conductivity. You can buy synthetic diamond heat-sinks right now.

Would love to have some diamond (man-made is fine) heat sink

If you mean an insulator between a power transistor and an aluminum or
copper heat sink, a thin aluminum nitride insulator would be almost as
good as diamond. Or hard anodize.

Really using the heat sink would require lateral heat spreading,
namely a big thick slab of diamond.

John, this would be used as a lower thermal resistance insulated
interface from case to heat sink. I wonder if you still need to use
the white bird shit on that interface ?
What's wrong with Mica?
Has been working for decennia here.
