No one is suggesting you install a fireplace, literally no one, so no, it is completely irrelevant whether you can do so.
The relative difficulty of solving the problems of excessive cold and excessive heat, however, is relevant. And that relative difficulty is cleanly and clearly illustrated by the relative simplicity of the simplest solutions to those problems, which are, respectively, a fireplace and an air conditioner. As I said before:
This has obvious practical consequences for the comparative difficulty of the problems; it’s much easier to fix ‘too cold’ than ‘too hot’.
The fact that a fireplace is simple has the obvious implication that heating is an easier problem to fix in theory, and that has the implication that it is probably also easier to fix in practice. And this is indeed the case.
