In my opinion, the county courthouse is a public building and the clerk is available, and obligated, to serve the public. The public is the collection of people who live and operate near the area and you have right of access to that building, and service from the clerk, as anyone else.
The issue is that the courtrooms in the building are always "booked solid" by members of the BAR who have mostly monopolized the time in that building. The obvious reason why that is welcomed and accommodated so enthusiastically, is that the members of the BAR generate tons of "money" for the county; they give the county plenty of business. That doesn't mean you are not allowed access to the court, it just means you have to find the few available time slots in order to conduct your affairs when necessary.
Now, as it pertains to recording instruments: I do not believe there is ANY claim of interest in your property simply because you decide to make a public record. The verbiage on your instrument dictates your claim; it is YOUR deed (act) and the original instrument gets sent back to you; it is YOUR property. The county clerk is the holder of the public record and only has a copy of your original which can be used to issue "certified" copies of your original instrument.
Think about that for a moment as it applies to "CERTIFICATE OF TITLE" for a car or the "CERTIFICATE OF BIRTH". Who holds the original? The holder of the original is the one who claims primary, and/or sole, interest in the property.
In my opinion, "registration" is a whole other animal; I believe that is tantamount to begging or petitioning the STATE for recognition of something.
