The truth is found in Scripture, not in men.
So why all the Protestant sects?
The truth is not in all of them, but it is among them. Our task is to discern it, with eyes and ears given by God for that which He has purposed from before the foundation of the world.
Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it. Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them." -- Matthew 7:13-20"Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:
If the buck-stopping point is the Word of God being interpreted by men, that is not "Scripture interprets scripture". That is man interpreting Scripture.

Notice that you didn't answer the question. Telling us that the truth is in all of them does not tell us why there are many instead of one, since (in your opinion) we do not need men or magisterium to interpret Scripture.
