Profession is literally 'a paid occupation' and homemakers aren't paid - so homemaking would be an occupation but not a profession. Furthermore, as the parent mentioned, there aren't really unmarried homemakers, except those who are independently wealthy. Someone may be a physicist or nurse and then _become_ a homemaker.
All this isn't to to say that homemaking isn't challenging or exhausting (it can be), just that it doesn't really qualify as a profession. I don't think the parent poster was implying it wasn't difficult, just that it doesn't fit within the framework of professions.
