Because your argument, if you are aware that you made it, is that it is “economically repugnant”. That is what you said, and that was your previous argument. You are now arguing with your own argument, saying “No. Why would I have any feelings towards what other people do? That doesn't make any sense.”
That is what it has to do with the discussion, that you are inconsistent and refuse to elaborate on your previous position by claiming it is other people’s position and that you “don’t care”.
