"If someone 2,000 miles a way sends you something that he thinks will harm or even kill you, do you have the right to get government to go after him and try and punish him, or at least stop him from doing it? Assuming that ANY government is legitimate, one of the few 'legitimate' functions is to protect people from other people (and organizations, like governments) who what to kill, harm, steal, or otherwise deny them rights (you know, like life, liberty, and the pursuit of happiness (which includes the right to own things!). Even most libertarians would say yes. But where do you draw the line?" (03/20/17)
