What do you mean by "art"? That can be a very ambiguous word. Politicians are not "artists". Doctors are not artists, neither are plumbers. They all have human connection. Every single career has "human connection" of some sort. So I really don't understand what you are talking about. Maybe you could explain?Anything that contains a 'human connection' is art.
Art can mean craft or trade or skill, but it can also mean a work of beauty.
Every single human would be an artist no matter what they do according to your definition.
