Your arguments are well and clearly stated. However, you're ignoring the issue of strategy that Stefan repeatedly referenced in his debate with Adam Kokesh. Your arguments will be useless in a nation that becomes beholden to votes dependent upon big government and you can't simply wish away that government. You need to win over a majority of the voting base in regards to private property rights and small government before you can address the issue of enforcing a national border. Europe stands as an example. As applied to the issue of initiation of force, a national border i.e. the U.S. border with Mexico is self-defense against those who would vote to have the U.S. government initiate force on their behalf.
