Some of the political right needs a serious revision of their knowledge of the history of their own nation. You can believe in small government and oppose the state in whatever form you wish. Just please stop pretending...
A. ...that all of the founders were unanimously in agreement with classical liberalism, believing in a small government. The Federalists led by Alexander Hamilton, were pro-business protectionists. They believed in developing the nation's export industry by protecting its own market from being outcompeted by British manufacturers, but also using the federal government to subsidise industry and improve the nation's infrastructure. He clashed with the Jeffersonians over this, and guess who won? Did America stay as a country of small farmers with minimal government as Jefferson envisioned? No, it became the foremost industrial superpower by the end of the century after almost a century of the highest tariffs in the world.
B. ...that they were principled men that believed in civil liberties at all times. George Washington was primarily sympathetic to his Secretary of the Treasury, Hamilton, over his Secretary of State, Jefferson. The cabinet was polarized between these two figures, and trusting Hamilton, he carried out the Whiskey excise tax as a means of paying off the national debt. He didn't cut spending, but he tried to raise tax revenues; a major violation of the free market.
What did John Adams do? He violated the Bill of Rights by passing the Alien and Sedition Act. Democratic-Republicans in some of the states, who saw this as a violation of their civil liberties and sovereignty, refused to enforce this. Adams responded to that by threatening to send the army to them, so they had to capitulate. Again, another case of big government.
What about Jefferson? Well not to mention his aggressive policies of federal-guided ethnic cleansing of Native American tribes, he also violated free trade by his embargo against Britain and France during the Napoleonic Wars. Before his presidency, every state was in charge of their military. Under Jefferson begun the effort to create a national armed forces, starting with the need to intervene against the Barbary pirates, leading to the creation of West Point. All of this shows that not even Mr. Libertarian actually principally carry out his ideologies, or so as he is portrayed as today as a blueprint of Ron Paul.
Madison later capitulated to Congress by agreeing to the necessity of a national bank by rechartering the Bank of the United States 2.0. Interestingly, he was actually active in opposing efforts by those like Henry Clay to pass subsidies and public works on improving America's infrastructure. But he failed.
C. ...that they were exceptional superhumans that has opinions that were so relevant, they applied to all periods. This, of course, is if you accept the premise that they were all in agreement with each other (which, as I demonstrated in A, they were not). The fact that they passed the second amendment is no indicator that the same principles should be applied now. If you advocate gun ownership, "it's in the goddamn Constitution" is not a real argument for that case. In the end, the founders were a bunch of wealthy intellectuals, a mixture of the early bourgeoisie and quasi-aristocratic slave owners. And the fact that they intended something does not make that opinion more relevant than anything. The original constitution has been violated over and over again by future governments, and just because you do so it doesn't mean Jefferson is going to rise up from the dead to choke you to death
