If you're going to reject the Papacy because the word "Pope" isn't in the Scriptures, you ought to reject the Trinity for the same reason. Plenty of a "Bible alone" groups already do. What makes you right, and them wrong? Remember, they claim to go by the "Bible alone" just like you do.
Like the rest of Protestantism, you pluck bits and pieces of Catholic tradition that you like -- stuff like the Trinity, Sunday worship, and the canon of Scripture -- pronounce it "Biblical," and adopt it as your own. There's far more attestation for the real presence of Christ in the Eucharist and the Papacy in the Scriptures than there is for any of the three things I mention above, but you reject both of them and accept the other stuff.
The ridiculous irony is that Sola Scriptura itself is not scriptural in any way.
Naw, I see the Trinity all over the scriptures...I don't see a pope anywhere...
