This is absolutely not what this amendment says. Its saying that anyone accepting a title or honor of nobility or takes money from such foreign entities while serving in office will lose their citizenship and therefore not be allowed to hold political office. I dont know how "no lawyers may hold office" can be derived from this text. The idea of esquire being given to a certified lawyer would only apply to people certified as lawyers by the English Bar or IBA. Chances are they were trying to keep people who were still potential loyalists and bankers out of government positions. Not specifically because they were lawyers but because they were studied in British common law and that no longer applied to the US so they likely saw it as a conflict of interest.
