What would be the harm?

[Angrboda]

I -want- to burn down the trailer, remember?  You're just asserting to the contrary to be contrarian, this objection has been dealt with multiple times.  It may be the case that we want this or that thing, but that is moral compulsion (and moral failure), again, not the same question as the underlying moral justification for a realist system.  You're not engaging with the proposition at all, just asserting otherwise.
