That is, create a work of art (as opposed to utility). Okay, art is nice, too.

But mixing artistry and utility is quite hard. Designing a nice, livable house, or a store, is a craft. Building fancy sand castles is a (pastime) art. But mixing the fancy free-form with being actually usable by thousands takes lots of work, resources, and time, because what you'd have to build is a cathedral. (If you think modern technology makes it simple, look at the history of building the Sagrada Familia in Barcelona.)
