...it was not an agreed act of cooperation between two parties.
Good find.
That is, indeed, a good catch. It does beg the question, though: Why is it OK to swap and then get permission, but not get permission then swap?
Apparently this is bad:
Duke: "Can I swap to you?"
Ruler "Sure!"
Duke: *swap*
But this good?
Duke: *swap*
Duke: "Is this good with you?"
Ruler "Sure!"
Personally, I don't see any meaningful distinction between the two. Yet we're supposed to consider one as good, and the other bad?
