Free trade is a step in the process of the destruction of local sovereignty.
When research is performed into the history of tax protest in Great Britain and the American colonies in the years leading up to the establishment of the United States of America, an important lesson can be learned from those historical tax protests. Specifically, the tax protests of those times can be found to have been in the majority in opposition to internal taxes, and rarely, if ever, in opposition to external taxes. And what was also apparently understood by the people of those times was that internal taxes were the stuff of the eating out of their substance, were a form of tyranny they felt was imposed on their lives, and this understanding was the catalyst that led to so many of their tax protests, until the time finally came when those people forgot the basic truths about their own form of government. History can well prove that the ideal manner in which to collect revenue for a government is by the laying of import and export duties, on goods and services imported into a venue and for goods and services exported out of a venue. The promotion of free trade must lead to the eventual imposition of additional internal taxes in a venue, eventually leading to the internal erosion of local sovereignty, while the untaxed trade brought into a venue from external sources will also contribute to the eventual economic weakening of local sovereignty from within that venue.
