How about we just make a giant heatsink that reaches into space instead. Then we can cool the whole planet. Coming up with crazy ideas is cheap, but the logistics are obviously impractical.

Look into radiative cooling. Basically this, but more practical. Several companies working on it: https://www.skycoolsystems.com/
This looks like it depends on the outside air to cool the coolant. "Radiative" can mean that too, not just IR radiation.
I don't quite believe this.
Is it really better than just using solar panels to run a heat pump?

A heat pump is a “ vapor-compression based cooling system” so that tech is an addition-to not an instead-of.
Whether it’s better probably depends on how expensive the additional efficiency is in practice.
> SkyCool’s Panels save 2x – 3x as much energy as a solar panel generates given the same area.
So if you’re area constrained maybe.
We had one. It was that sulphur used in shipping fuel.
