Not only that but the remainders can consent to provide labor. They could work for the plurb doing the things that plurbs can't do. I thought that's where they were going with Zosia saying they would cook a pig if Mr Diebate killed it himself.

I thought they were going to ask Carol and the others do a Richard Matheson thing. If the non plurb do something that they don't know is causing harm, and the plurb aren't the ones directly causing the harm, then there is no problem for their logic. They've shown they can do indirect harm (speeding up P-day causing almost a billion to die) and that they forgive Carol for unknowingly doing harm (killing millions by losing her temper).
