Unless you're thinking about large homes, these empty square meters are absolutely needed and healthy. You need space to walk in your home, it's much more pleasing psychologically than clutter (or even slabs of "organized" stuff), and reduces claustrophobia. So yeah, the space constraints can absolutely make some hobbies, or owning too many physical books and media etc., too costly.
