As a strong free will sceptic I agree that you can never reasonably tell someone “you ought to do X over and above Y”.
However, it makes complete sense to me in a purely deterministic world to make one small addition to the phrase: “you ought to do X over and above Y in order to achieve Z”. The ought has no meaning without the Z, with the Z representing the ideal world you are deterministically programmed to want to live in.
Lmao Sumner is straw manning hard with this one
