You're missing the point. Once you have a subsistence diet (i.e. the cabbage, egg and rice), better and/or more food isn't strictly necessary. It's just desirable. So your tablet argument becomes: "if I can't afford the foie gras, I shouldn't bother with a decent cheese plate either", which is obviously wrong for a variety of reasons (including that some people just don't like foie gras).
