1.
The Bible Never Claims to be the Sole Authority
Chandler, do we want to deal with truth or not? That is the first question. The second question is "Do Jesus and the apostles call Scripture 'The Word of God'"? The third question is "Does the Word of God signify that this is GOD'S TRUTH"? The Lord Jesus Christ said that
"Man shall not live by bread alone, but BY EVERY WORD THAT PROCEEDETH OUT OF THE MOUTH OF GOD" (Mt 4:4). Have you given this statement the consideration it deserves? Since every word of Scripture is a word from God, we have 2 Timothy 3:16,17 (which you quoted) to establish WITHOUT THE SHADOW OF A DOUBT that
Scripture (the Bible) is the sole authority in all matters of faith, doctrine, and practice for the Christian. If you have any doubts study Psalm 119 very carefully. So your postulate #1 is FALSE.
2.
The Bible Endorses Holy Tradition
No. The Bible does NOT endorse "Holy Tradition" (the traditions of men) but "the traditions of the apostles" (the revelations of Christ to the apostles). The Greek word
paradosis has been translated as "tradition" in the NT. It means "that which was handed down". The Lord Jesus Christ taught His apostles -- OUT OF THE SCRIPTURES -- for forty days after His resurrection and before His ascension (Lk 24:25-27; 44-48; Acts 1:1-3). He also taught Paul directly through many revelations (Gal 1:11-17). These teachings were verbally handed down by the apostles, and then written down in the New Testament. Therefore THERE CANNOT BE ANY CONTRADICTION between "Holy Tradition" and Scripture. But when we examine "Holy Tradition" in the light of Scripture, we see a lot of the traditions of men incorporated into that supposedly authoritative tradition.

The Early Church Fathers Never Advocated for Sola Scriptura
If you read the writings of the Apostolic Fathers, their sole authority is Scripture.
Later on, the ECF themselves introduced the traditions of men into "Holy Tradition". Here's how Polycarp compares himself (and others like him) and his words to the apostle Paul:
For neither am I, nor is any other like unto me, able to follow the
wisdom of the blessed and glorious Paul, who when he came among you
taught face to face with the men of that day the word which
concerneth truth carefully and surely; who also, when he was absent,
wrote a letter unto you, into the which if ye look diligently, ye
shall be able to be builded up unto the faith given to you,
The apostle Peter equated this "wisdom" of Paul with Divine inspiration (2 Pet 3:15,16)
4. Sola Scriptura Produces Bad Fruit
Right. Only if you believe the propaganda of the "Traditionalist" churches. The truth is quite the opposite. Millions have been saved (and are being saved) through the preaching of the true Gospel QUITE APART FROM "HOLY TRADITIONS". On the other hand we have hundreds of pedophilic priests coming out of "Holy Tradition".
5. Sola Scriptura is Simply Not a Feasible Concept
Says who? If it was perfectly feasible for Christ and the apostles, why should it not be feasible for all Christians today? After all it is the living Word of God (1 Per 1:23-25):
Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever. For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.
What do we see here?
1. We are born again by the seed of the Word of God
2. It is an incorruptible seed
3. It is a living Word and an abiding Word
4. The Word of God is eternal -- endureth forever
5. The true Gospel is the Word of God.
Does this establish "feasibility" or not?
So instead of refuting Sola Scriptura, Christians should be embracing the Bible and Bible Truth -- not the traditions of men. The Reformers did not go far enough. They should have discarded everything that could not be supported by Scripture. They failed to do so.
