As we are furhter oppressed by the state to give up our privacy and liberties should we wish to travel, the following passage made interesting reading..
What is a passport? A universal recommendation of a traveller's person, a certificate of security for himself and his belongings. The treasury, whose nature is to spoil the best of things, has made the passport a means of espionarge and a tax. Is it not to sell the right to travel and to move about?
PJ Proudhon - 1840
