I think that this is quite an inaccurate statement about the way that the word art has been used "historically."
Just for fun I Googled "The Art of Fletching." Google returned 2,770,000 results in 0.33 seconds. I think it is incontestable that from the origins of the word as "manmade rather than naturally occurring" to the present, the term has been attached to an astonishingly broad array of objects and creative activity. For instance, just because something is useful does noot disqualify it from being referred to as art.
A Grecian urn is made to store olive oil. This utility did not stop the poet Keats from rapturous praise, in particular comparing the art and beauty of a well-turned urn to music with these words:
"Heard melodies are sweet, but those unheard
Are sweeter; therefore, ye soft pipes [the evocative lines of the Grecian urn], play on;
Not to the sensual ear, but, more endear'd, pipe to the spirit ditties of no tone."
OK, I'm off to Google "The Art of basket weaving."
