VB says I "changed the reader’s argument in a way to trivialize it." I disagree that I changed it, but I agree that I trivialized it. While I will respectfully note that many, including church leaders, have accepted and even taught it, I think this argument is absolute nonsense. I strictly believe that we should keep our doctrinal basis in the scriptures, and consult outside sources—official or unofficial—insofar as they supplement the canonical record. But, as Harold B. Lee taught, "If anyone, regardless of his position in the Church, were to advance a doctrine that is not substantiated by the standard Church works, meaning the Bible, the Book of Mormon, the Doctrine and Covenants, and the Pearl of Great Price, you may know that his statement is merely his private opinion." I do not believe that any speculation about the mechanism by which Lucifer sought to take away agency (and thus save all men), is doctrinally supported.
Thus when the question asker specifically said that Lucifer sought to use the power of government, I was quick to point out that this claim was, like similar claims I had heard in similar arguments, entirely unsupported by the standard works.
President Faust's suggestion that Satan sought to use force in his plan is plausible, but doesn't tell us much. It would take force to make us mindless automatons, as W&S speculate. It would take force if Satan were to use some sort of governmental hierarchy as others speculate. Or there might be a third option, I don't know.
To the quotes Vorpal provides suggesting we preserve agency at all costs I add Elder Oaks balancing take on the subject (source):
"Few concepts have more potential to mislead us than the idea that choice or agency is an ultimate goal. For Latter-day Saints, this potential confusion is partly a product of the fact that moral agency--the right to choose--is a fundamental condition of mortal life. ... But our war to secure agency was won. The test in this postwar mortal estate is not to secure choice but to use it--to choose good instead of evil so that we can achieve our eternal goals. In mortality, choice is a method, not a goal.
Of course, mortals must still resolve many questions concerning what restrictions or consequences should be placed upon choices. But those questions come under the heading of freedom, not agency. ... We are responsible to use our agency in a world of choices. It will not do to pretend that our agency has been taken away when we are not free to exercise it without unwelcome consequences.
Because choice is a method, choices can be exercised either way on any matter, and our choices can serve any goal. Therefore, those who consider freedom of choice as a goal can easily slip into the position of trying to justify any choice that is made."
And I'm going to appropriate the conclusion of Elder Oaks point (in the context of abortion) as my own point in the argument of welfare: "My young brothers and sisters, in today's world we are not true to our teachings if we are merely pro-choice. We must stand up for the right choice." Similarly, it's not enough to stand up for the right to choose whether or not to take care of the poor. We must stand up for the right choice: making sure there are no poor among us. We will disagree on how to do that, but some of us try to do that through legislation, we are not taking away agency.
On Ludlow: That satan currently tries to destroy our agency through any means possible is beyond dispute. Of course he does. But Ludlow's question doesn't address satan's premortal plan, which makes it irrelevant. As far as I know, satan's premortal plan and current plan must be entirely different since they are to opposite ends. Remember, Satan doesn't want to save anybody anymore. One thing the two plans obviously have in common is the destruction of agency, but I was careful to address at length why I didn't feel compulsory welfare to be a destruction of agency any more than any other government act—or especially compared to the agency-limiting effects of poverty.
The problem, VB, is that you seem to be asking me to do something that's rather hard to do: respond to arguments that weren't provided by the questioner. I tried to make my answer broad enough to address the many different forms of that argument I had heard. I don't believe I erected any "straw man"—if there was a straw man, it was the one erected by the questioner's poorly-argued query. I tried to deal straightforwardly with the argument as presented. I could have taken another approach, but hey, I don't get paid. Good idea for a future draft of my rant, though.
