I wasn't implying anything about forgery issues whatsoever. Bob's legal document could be licensed by his state for all I care, but what I'm implying is that the laws of the land, included those by which variously designed legal documents are made, don't
REALLY have any moral force---implying that Jane 'should' recognize it---unless there is some kind of tangible source of morality inherent somewhere in Reality (that's Reality with a capital
R, a notion that I deem to be opposed to the more colloquial use of the term of "reality" [with a little
r] as we each may mistakenly perceive it to be).
So, my gripe is that I think that just because Bob has a legal deed to waive in Jane's face, this doesn't mean much if there is no Supreme Moral Source (God
or Platonic Moral Form
or fill in the metaphysical blank) ultimately backing the various hierarchies involved in legal as well as moral interpersonal decision making that can go on between people in any land, anywhere.
And if there isn't a Supreme Moral Source, then our simply acting like there is one doesn't make it so, and our simply saying that we're all going to be "rational" anyway (as rational as perpetually contentious and warfaring humans can be, I suppose) in trying to come to legal conclusions and agreements doesn't make them real, either. Yet, if we're like Kant, we'll definitely see the need to posit such, and maybe even hope for such.
But sure, if we want to all play dress up and pretend that our laws and moral ideals without God mean something real, well then, let's have at it!
