It's not like we get along fine in space et al because we put up with discomfort. Have you actually considered your examples? Space is survivable in part because the suit keeps you warm. Under water is much the same way; stay in the water long enough and you need a drysuit or wetsuit to stay alive. Freezing environments? You wear seal furs.

The point is, talking about how we can survive in freezing environments does NOT demonstrate that climate control (or rather, local microclimate control around your body) is just creature comfort.
