Ah! At last we agree that the government gets it power by the consent of the people, which gave their consent to relinquish their "natural right" to due process!
One problem: women, Indians, and slaves didn't give their consent and their unalienable natural rights were nonetheless NOT granted, and without their consent.
We agree that the government gets its power by the consent of the governed, but you go further to make the incorrect claim that the government is the source of natural rights.
And slavery does not exist, while women, Indians, [and blacks] are all in a position to give their consent.
