These people have done well with the measure of Grace and knowledge of God given them. That said, I challenge how that "proves" Sola Scriptura; given only Scripture and the Natural Law that already existed in the hearts of these people, neither I nor anyone else could expect they would come up with something other than a system based only on Scripture. Had they been given the Faith in its fullest as it came down from the Holy Apostles, they would have had a church that resembled the Catholic or the Orthodox Church (if not a part of one of those two Churches).

Seems like quite a LOT of rather brazen
ASSUMPTIONS,
INFERENCES,
EXTRAPOLATIONS
AND
BIASES . . .
to me.
That said, one large assumption that you made is the one that became the title of this thread: that a group of people, given only the Scriptures (via audio) and that have formed churches that fit a model that those who believe in Sola Scriptura consider to be Biblical proves that Sola Scriptura is true.
What I'm asking you is how giving a group of people the Bible in a vacuum, with no interpreter or outside influence, *proves* that Sola Scriptura is true. The result is the one that would be expected, when all you have given them is Scripture. I'm attempting to say (although perhaps not well) that if these people had lived in the same historical context as the Apostles and the rest of the Early Church, their theology and ecclesiology would have been that OF the Early Church. You neglected to answer that challenge in your prior response; instead you chose to dismiss it.
I think marshmallow's point bears consideration as well... what happens when these individuals begin to stray off or disagree, when there is no authority to guide them?
