What happens if someone refuses to do any chores in a shared household? There are already plenty of situations where people do work for free because it's in your own interests. In groups like households people take turns taking out the bins and cleaning. In a communist society people will take turns doing the necessary work. If someone refuses, maybe something is wrong in their life, and they need help. At the end of the day, there's no economic coercion in a classless society. If one in a million people don't work for no understandable reason (disability, depression, personal issues, etc) then let them. What else are you going to do? Work or starve? Incarceration? The point of the universal emancipation that communism brings is to do away with those evils.
