Yeah, I recall how the conversation went. Let me ask again: why do you think that an ethics system based on rights, positive or negative, is only about rights? Locke did not promote the idea of positive rights, but his philosophy did not begin and end with the idea of negative rights.
The preamble merely lays out the case for the government and emphasizes that the powers of the government are derived from the consent of the governed. It does not grant any powers, and those two little words certainly do not trump the rest of the Constitution or destroy the notion of enumerated powers - although they have been seized upon to do just that, as Madison predicted. But if you want to argue with the guy who wrote the Constitution, that is your prerogative.
