Anti-work is inherently reactionary. It tries to shift the blame away from capitalism and onto labor itself, that we shouldn't oppose bourgeois labor relations but should oppose work as a whole. It also gives right-wingers an easy win since it makes "the left" look like buffoons who think you can abolish work, and fits into their stereotype of a lazy hippy leftist who refuses to get a job. You can't reform a sub that is based on a reactionary premise from the get-go.
