You're conflating craftsmanship with art. There are literally factories in China where painters paint replicas of classic art works at scale. They paint hundreds, even thousands of such pieces every year. They're undoubtedly very skilled painters. But would you call their work "art"? How much time and effort something takes has no bearing on whether or not it is art. Something that takes 5 years to make isn't automatically better than something done in 5 minutes. Painters like Picasso and Matisse were also classically trained and had all the skills to paint like the painters of old. They just chose not to.
