Because the concept isn't capacious enough to describe human existence. Your definition seems to hold that self-sufficiency and nonagression are the prime characteristics of human being.
Well. Anyone with eyes can tell you, this is hardly the case in practical reality.
And then, you and I both complain when these exemplary and hoped-for conditions do not hold. As they quite usually do not, these days.

I won't respond until you've had a chance to provide your whole answer. Remember, the question is how the self-sufficient individualist who never uses coercion against another is the cause of personal and social disorder. (By the way, Jesus and Paul [after his conversion] were both self-sufficient individualists who never used coercion against anyone, [those trouble-makers].
Enjoy your supper. (I'm in New England, the evenin' meal is always suppa'.) Hank
