Intuitively, the system of private judges accomplishes its objectives by bundling the services which are valuable to the individual trader with services that are valuable to the community, so that a trader pursuing his individual interest serves the community's interest as well. Unless a trader makes appropriate queries, he cannot use the system to resolve disputes. The requirement that the traders make queries provides an opportunity for the judge to collect payments for his services even if no actual disputes arise.
