I mean, the people who drew simple cave drawings probably didn't expect people to view their doodles as art pieces thousands of years later, but here we are.
Gatekeeping art is silly because it's not just wrong to do but its such a futile thing to do. Art isn't just what people will remember, it is expression! And it's all around us, from beautiful architecture, to statues, to murals, to kids drawing on the sidewalk with chalk. It's in the biggest music halls, all the way to the local dive bar or coffee shop hosting a singer-songwriter who just likes to sing his songs on a Friday night to a couple dozen listening ears. It's in the giant cineplexes playing the biggest films, to the small theaters that show foreign or low budget films, all the way to the phone someone is holding on the bus plays a random YouTube or TikTok video.
Not all of it has the same value or meaning, but it's all still art. Don't try and gatekeep it, or try and tell someone that what they created isn't art just because it doesn't appeal to you.
