If you automate away jobs people like, their labor gets re-routed to other things they don't like. Like not being able to sell illustrations and turning to being a cashier
I don't disagree with your central point, humans were creating art hundreds of thousands of years before they started farming at large scales. Creating art is a fairly fundamental aspect of our species.
Farming is an ancient human practice. It would be a huge loss to society if we forgot how to do it with our hands, without automation.
