Perhaps you could try to find two other members who would agree to going through the process of calling an initial meeting for forming a Statutory Road Association. Do you think if you called such a meeting, and perhaps had someone come to explain how it works to those members who show up, possibly you could get one established? It sounds like the current association is unenforceable, and with members figuring that out, chances are that soon you will not have enough dues coming in to cover expenses. (I speak from experience.) Those who are no longer paying may be your best allies, as it sounds like they are objecting to the lack of accountability.
