Also it depends on where in space you are. Not all space is cold. Even remote space. Within humanity's life time our solar system has traveled into the remains of a super nova that's millions of degrees hot. The solar wind keeps it from interacting with us (like a shielding flux). But if you were in interstellar space there is no guarentee that your equilibrium temperature would actually be cold. It might take a long time to heat up because the partical interactions wouldn't be frequent but you wouldn't exactly be conducting heat outward.
The other way to drop temperature is to shed gas and pressue yourself. So maybe if you outgas a ton into space you will cool off. But that would be water which has its own problems. Either you are wet and warm or cold and evaporating/sublimating.

That is a misunderstanding. By the time solar winds from such stars reach interstellar space or our system it's cold and almost indistinguishable from pure vacuum.
Once you're out by around Jupiter I reckon or beyond it's going to be cold even in the sun because at that distance our sun just acts like a big star in the night sky rather than a sun.
