The solution, of course, is to make legal arguments a class of intellectual property.

If a lawyer wants to cite a precedent, he's got to pay. Using a parallel argument without explicitly citing the precedent is a tort, and may be subject to lawsuit.

This will tie up all the intellectual property lawyers who will start suing each other. At that point the rest of us can go on with our lives.

(At least in countries with a common law based legal system...)
