You do realize that if any of the founding fathers came back today, they would probably be considered small-l libertarians. Not as far out there are the official Libertarian party, buy way, way, way (way) to the right of today's typical conservative.
The Federalist Papers (and anti-federalist papers, written by people like Patrick Henry who opposed ratifying the Constitution) really sheds a lot of light on how the founders thought. If you think raising a child in a "libertarian society" would be "hell," then you think raising a child in the society envisioned by our founders would be "hell" as well. Because, the society envisioned by the founding fathers (when it comes to the role of government) is a libertarian society.
Each state could go fully communist as long as that state did not violate any of the BOR's. Each state could be a Libertarian paradise. The states should be 50 laboratories of governance. If you don't like it in one state you used to be able to vote with your feet. The republic has been so bastardized that it is now under the thumb of the FEDs which are socialist. The original intent of the USC was to prevent that from happening. As such the USC is an utter failure. I totally understand what the original intent was, so spare me.
