Obviously if they believe “just me and my Bible” to the extent you are describing, they would find it impossible to meet together, spread their views, or “stand up and be counted” in any way. Most of us would find it nearly impossible to be sure they were
clearly Christian, if they don’t have any assemblies (or baptism?) or any responsible teaching…of course we hope the grace of God works miracles in all hearts, no?
But I did grow up in a Baptist pastor’s family, and I can tell you that we believed that “The Bible is the sole rule of faith and practice for the Christian” and that the role of a church was to proclaim, evangelize, teach, etc. so as to inform the individual conscience–but that the whole teaching authority remained in the Book itself, and the liberty (and responsibility) of each individual believer was to personally come to understand and be convinced of each truth in the Bible.
Now, I still don’t think it’s bad to say that each person ought to learn the Bible thoroughly, or be called to our responsibility to assent to the truths we are taught, but I don’t think it works out very well when each of us bears whole and sole responsibility for that judgment–which is the unfortunate practical consequence of making the Bible the sole rule of faith and practice for each separated believer, rather than treating the Bible as the written core of the depositum fidei, wholly inseparable from and essential to the Tradition. In my new Catholic faith, I am permitted to modestly understand my limitations of competence, and resign to the Church’s Magisterium that measure of my responsibility of articulate and practical assent to the fulness of Revelation that I cannot yet manage, while knowing that the Magisterium, as a Teaching Office, will by the Spirit’s work lead me into all things. In God’s good time. Not in a series of wrenching crises (as many of us experienced our Fundamentalist/evangelical lives prior to coming Home).
Throughout Protestantism, where it is competently taught (see: conservative/evangelical churches), the belief that “the Bible is the sole rule of faith and practice” for the individual (or in some forms for the church) is an essential distinctive of the tradition(s). See
monergism.com/directory/link_category/Five-Solas/ for a discussion of the five “only” or “alone” assertions which are comprised in the essence of “Reformed” teaching. Here’s a discussion of this principle in terms very like those I was taught:

So there are very few of the variety you describe. And Benny Hinn is … not a competent Protestant teacher, and not a believer in Sola Scriptura, as he believes he personally can make up personal prophecies whenever he feels “led” to do so, with his own made-up “apostolic” cred.
