Because read the links.
So that I search through dozens of pages of posts to find your answer to a question which you could easily provide right now? No thanks.
The whole point is nothing you say (i.e. promise) prevents you from simply deciding to not do what you are ordered.
That’s true. Likewise, when I sign a loan contract agreeing to repay the lender in the future, does that prevent me from deciding later not to repay him? No. Does that fact mean that the loan contract is invalid? No. The ability to change your mind about a contract does not make the contract invalid. I suppose your idea is that what the contract purports to transfer ownership over (the will) is not actually transferred, evidenced by the slave’s ability to change his mind later. And such a contract would indeed be invalid (though not quite for the reason you cite, but no matter). HOWEVER, that is not what a VS slavery contract is. A VS contract transfers ownership over the body. That is not the same as control over the body. The fact that the slave can later change his mind indicates he never transferred control over the body, it is no way demonstrates that he never transferred ownership.
Basically you’re alleging that one can surrender control of (i.e. alienate) something that is inalienable from him…control over his own will and person.
No pro-voluntary-slavery (VS) libertarian is “alleging that one can surrender control of…[one’s] own will and person.” We are alleging that you can sell your own body: transfer ownership of it. Control has nothing to do with ownership, except in the case of initial appropriation through homesteading, but that has no bearing on the question of VS.
You cannot “sell” (that is, transfer ownership of) your will
Correct.
because you cannot alienate yourself from it.
No, because the will is not property, and cannot be owned: and cannot therefore be sold. No non-physical thing can be property.
The new “owner” of your will doesn’t really own anything
Who said anything about owning the will? VS is about owning the body.
He isn’t controlling you. You are still in complete control.
Correct.
You’re just voluntarily choosing to obey orders. This is not slavery.
You are confusing voluntary choice in the ethical sense with voluntary choice in the physical-metaphysical sense. A slave picking cotton in the antebellum south is making voluntary choices in the physical-metaphysical sense (i.e. he is not an automaton which the master can move at will), but he is not making voluntary choices in the ethical sense (because he is acting under coercion: e.g. the threat of the whip).
But not all violence is aggression. When is violence not aggression? Violence against one’s own property is obviously not aggression (e.g. beating my dog), nor is violence against the property of another when one is in the pursuit of one’s own property (e.g. breaking down the door of a thief to retrieve my stolen TV set).
It is certainly violence for the master to whip the slave, but is it aggression? First, to clarify, “whip the slave” means “whip the slave’s body.” The master is whipping a piece of matter, he is not whipping a will or a mind or a soul or any other non-physical thing. Now, if the slave’s body is the property of the master, then the master is not aggressing. That is the claim of pro-VS libertarians: the slave’s body is the property of the master, and so any violence or threat of violence against that body is nothing but the master using his own property: it cannot be aggression. The slave can no more object to the master whipping the body than I can object to you beating your dog: it’s not my property, it’s yours, to do with as you please.
The minute you decide to not obey an order, you have illustrated the fact that was true all along…it is in fact you who is owner and controller of your will and person.
Again, you conflate control of the body and ownership of the body. This is wrong. The former concerns physical reality. The latter concerns ethics and law.
It’s my assumption that if you are presented with a logically sound reasoning, you will not deny it’s validity. Evidently I assume too much.
You do, namely that what you present is logically sound reasoning.
N.B. Perhaps some of the problem here is that when anti-VS libertarians think of “the body” they think of it in first-person perspective, whereas pro-VS libertarians are talking about “the body” from the third-person perspective: i.e. as one piece of matter in the world, which is capable of being owned and sold like any other.
