Does it follow that the house has nothing in common with art and is architecture not to be included in the arts? Only a very small part of architecture belongs to art: the tomb and the monument. Everything else that fulfils a function is to be excluded from the domain of art.
I don't see that any buildings should be excluded from the term architecture as long as they are done properly.
As the only girl growing up among three brothers I was always afraid of being excluded. If there was a game to be played a sport to be learned a competition to join I was on my feet and ready. I didn't spend much time alone for fear that I'd miss out.
