We have at least established that very boring pieces, such as Andy Warhol's Empire, Kazimir Malevich's White on White, and John Cage's As Slow As Possible, are not art.
I think you're saying bad art is still art, but I'm unsure what to do with the second sentence. I'm toying with "an encoding of art is not art", which might mean that art has to be available to an audience.
