The methodology isn’t the same—Yvain’s methodology is to give people a Brand New Thingy that they can latch onto, yours seems to be reinventing the Old Thingy, preserving some of the terminology and narrative that it had. As discussed in his Parable, these are in fact very different. Leaving a line of retreat doesn’t always mean that you have to keep the same concepts from the Old Thingy—in fact, doing so can be very harmful. See also the comments here, especially ata’s comment.
And that is why I disagree with this part of your argument:
if you agree with Yvain’s argument...then you agree with mine
