Many great reasons raised to explain why the current system persists so its clear to me that there isn't just a single roadblock. One reason, in my mind, is the challenge of reaching consensus. Even in small groups this can be problematic and more so for an entire population. It frustrates me no end that often small disagreements in the details of an idea is enough to prevent any positive change, even though at a macro scale the idea is good and universally supported.
