Statist Query: Why Do You Need ... ?

Fallacy:

(Often with firearms, or firearms of a type, a magazine of a particular size, etc.)

E.g., "Why do you need a 30-round magazine anyway?"

Response:

Why do you need access to the Internet? You don't. Yet you have it anyway. Asserting "You do not need X" even if it is true (define "need"; need to live?) is not a justification for stealing or infringing a person's right to obtain or manufacture X. (DR)

My favorite response is, "Why do you need a fire extinguisher?" Obviously, in case of emergency. [HB]
