Government has the legal authority, AND obligation I would add, to enact measures that preserve the security of the state. This libertarian view of "freedom" is flawed from it`s start. Freedom doesn`t mean any of us can do ANYTHING, and dare someone to stop us. Freedom comes with the responsibility to be a good citizen and contribute to the productivity and security of the state. You already KNOW this.
That sounds Marxist when I read it.
