This seems to be a troublesome issue of how we use the word 'art'. That's a language issue more than anything. Gaudi wasn't an artist, he was an architect. Certainly, architecture can have artistic flair in a big way, but there is an exclusive definition of 'art' that describes the types of works that serve a singular purpose, by people like Damien Hirst, Andy Warhol, Banksy, etc. these works serve one purpose and that is to make the receiver think in different ways about society, It doesn't serve any other purpose, such as shelter from weather, or advertising a product, or telling a story, or as a backdrop for dance, etc. We call those other things, architecture, design, comics, music, etc. They are of course 'arts' and considered under that umbrella term and can be thought of as artistic, but they aren't 'art' in the singular sense. I think this is a discussion that continually happens though, so I'm just conveying how I've come to understand it and what makes logical sense to me.
I think your prompt 'create art' would be an interesting exercise. would you like to present any images?
