It’s a cultural thing for white people. Hell, I’d say that it’s one of the only things that’s truly white culture. When the word “art” gets used on something, it’s basically the same as anointing it. Any and every drawing, sculpture, text, video, and song is “art” by default. And some take it further to define everything made by a person as “art” too. Even though it’s vague as hell, it’s a deadly serious topic.
I’m not saying that other cultures don’t have similar ideas, but that it’s weird the way that white people universally agree that protecting “art”, whatever that is, is of the utmost importance.
Funny you say that because Unitedstatesian is actually the proper term in Spanish (estadounidense). Besides that, I’ve heard people say Americano/a or yanqui. I’ve never heard usaeño/a
