James M. Buchanan

Let those who would use the political process to impose their preferences on the behavior of others be wary of the threat to their own liberties, as described in the possible components of their own behavior that may also be subjected to control and regulation. The apparent costlessness of restricting the liberties of others through politics is deceptive. The liberties of some cannot readily be restricted without limiting the liberties of all.
