It is the right question to ask. The idea that moral questions should have a market value is itself a moral failing, so assuming you want moral principles to rule over the design of your economy (which.. you'd better; otherwise slavery is permissible), you should not allow such things to be up for debate.

Although perhaps your disagreement is over whether this is a moral issue, in which case, fine, but let's be clear that that's what we're disagreeing over.
