To be clear, I’m still advocating for my definition. I inferred, correctly or incorrectly is the question I posed to him in that post, from John James’ statement “If anyone would like to explain how ‘increasing one’s wealth at another’s expense’ is not stealing, I’d be interested to hear it,” that he is implying that wealth includes the value of the sum of one’s economic goods- if not, he’s arguing that, in inflating, the inflating agency (in this case, the state) is aggressively seizing the property of others; that is, unless there is some other option, for which has not yet contended.
Aggression here denotes an action that violates the legitimate (legitimate defined below in parentheses) property rights of others; it may take the form of violence (me running up to you in the street and punching you in the face would violate the property rights you have to your body, assuming you had never before aggressed against me or my property), but violence (in the sense of physical confrontation, if this is what you mean) is not necessary for an action to be aggressive by itself. For instance, you mug me, steal my watch (again, assuming that it is legitimately my property), and run off with it on Monday; on Tuesday, I see you, restrain you, and take back my watch. In scenario, you aggressed against me by violating my property rights to my person, by mugging me, and the property rights I had to my watch by stealing it. My taking back the watch does not constitute an aggressive act, and is consistent with the Non-Aggression Principle, because it was taken in defense of my property and the violence I used to take my watch back (restraining you) on Tuesday was less than the violence you used, initially on Monday, against me (physically beating me).
For instance, if you weren’t home and I broke into your house to steal your televsion, this would be a violation of your property rights to your house and your television, assuming you acquired them legitimately (i.e. through homesteading them, producing them, or acquiring them through voluntary exchange), and would constitute an act of aggression; namely, theft. Such an action may not be aggressive in the sense that I pried the television from your hands or fought you for the television and took it in your incapacitation, but it is aggressive with respect to the definition as it applies to the Non-Aggression Principle and property rights.
