You're describing a thermal balance. Temperature is a property of matter which doesn't exist in a perfect vacuum. That said, the space around ISS is far from a perfect vacuum (atomic oxygen sucks). In any case, the typical temperature model starts to breakdown with increasing vacuum.
Sure, but in any practical sense it is a temperature. It would be silly to say space isn't cold (or hot depending) from a regular person's perspective. Thermal balance creates an effective temperature, even if it wouldn't be described as a temperature within some technical frame of reference.
That's a fair point.
